Hello,thanks for the compliment. Yes,the car is going vintage racing. I'm building for group 6 A/P, which is lots of big block cars, Camaros,Vettes,Cobras, that sort of stuff. My car is being built as a early 70s factory Trans Am Mustang, but with a Boss 429. I do also have most of the parts to build a Boss 302 engine which could easily be swapped in for the Trans Am class. They are still limited to 305 cid. 

That is AWESOME!!

Reading about your build stirred some pleasant memories from the Laguna Seca racetrack many years ago. I got to see the Penske-Donahue Camaros. I met a guy who had the "best" job in the world (I thought at the time); he maintained and prepped vintage Trans Am Camaros (don't recall how many 2 or 3 maybe) for a guy that travelled the vintage race circuit. He always travelled ahead and had the cars ready for when his boss the driver showed up. His boss owned a big company which he was considered an employee of and received a salary, medical/dental and retirement. 

Sorry for the thread derail. Vintage Trans Am racing is the best racing. Wish I had the time, money and skills to be involved. If you ever make it out west to run your Mustang I'll volunteer for pit crew duty. I can turn a wrench.

That is some real nice fab work. It's fun to watch your progress.

I'm really glad that people like what I am doing. It's just me in a small workshop striving to put out the best possible end product.I really am trying very hard to have an end product that looks like Kar Kraft built it.That being said I have bushings.Rear sway bar bushings that you can't buy.I have a friend that is a machinist and works on turn of the century gas engines.I asked him if would like to make the bushings.So a week later I have nylon bushings for a 5/8 rear sway bar.

Pretty sweet! That's a real well laid out rear suspension. It's gonna be difficult to route the tailpipes though! LOL!!    :rofl:

Some of the vintage Trans Am do have deducible limits on the cars. I have no idea where you intend to run but keep that in mind. Check to see if there are limits.

When a man is in the woods and talks and no women are there is he still wrong??:P

Hi again,upon the completion of another task I have some pictures. I have C-notched the frame over the axle.This car is going to be rather low and I do not want metal objects hitting other metal objects. I took inspiration from a 70 Bud Moore Mustang. I raised the frame height by 1 inch. Then the recess on the bottom is for traction bar mount clearance on the axle.That adds another 3/4 inch in height.And it is 1 inch deep.All the brackets and parts are made from 1/8 inch and all have a curve in them for added strength.When I raised the frame it left the shock crossmember hanging down 3/4 of an inch so I pie cut and sectioned the ends so it fit back up to the frame.

Be honest and simply say you're addicted to argon gas! :D

Sniffing that gas myself at times a little, I must say you've done some impressive work here!!
That car will not twist easy for sure!!

Moving right along,we have the over rider traction bars done. They're made from 1 1/4'' DOM,with left and right threaded ends for 5/8'' chromoly teflon coated ends.I can now preload the rear and keep the pinion angle change to within a degree or so.Goodbye wheel hop and brake hop.And speaking of brakes here are the rear,11.75''x0.810 rotors and 67 Mustang 4 piston Kelsey Hayes calipers.The brackets are 1/2'' plate that I threaded for 1/2x20 bolts.Almost done with the rear suspension.Just have to finish the axle bumper mounts.

Man you are killing me. I walk by the car I want to do track days with each day and wish I could be working on it. Surgery soon I hope it works. Unlike you I will be using some of the latest steels and can go half the thickness and still be stronger and lighter. Hope I live long enough to run a 351 against your Boss 9. Glad you are making such great progress.

I hope your surgery makes your quality of life much better.As for working on the car,I over build everything,so I never have to think about it again and move on.My wheelstander took way,way too long to build.This one I am pushing for about less than 2 years for a completed chassis.It should be fun to hear people say"what the hell is that" as the car gets backed out of the trailer.Are you going to run a vintage drive train in your car? Like a 4 spd  and 9'',or a more modern set up?

For the life of me I can't figure out why no after market company has come up with an actual bolt in one piece export brace for the 71-73 cars.So here is part one of me doing it.I cut the ends off the factory braces and made new ends out of 1/8''. Now they bolt under the shock bracket and spacer,just like the 64-70 one  piece braces.I'm going to wait to build the connector at the firewall because I have not yet settled on 1 or 2 carbs,air box or Ram Air,and there will most likely be clearance issues.so I will make it one piece after the carb situation is sorted.I chose to reinforce the stock shock mounts on the top with an 1/8 washer.If the car starts to beat out the bushings I will switch to the 67-70 shock mounts.I also have the rearend bump stops welded in.I used new bumpers for the front of the car,since bolting them in is easier.

More progress. Today we have front brakes and sneak peek at what she's going to look like. The front brakes consist of 71 disc hubs,68 T-bird rotors,69 Lincoln 4 piston KH calipers,Street or Track Trans Am caliper brackets,with 3 inch ARP studs all hung on 70 drum spindles. the rotors are 12x1.25'',this is the largest brake set up you can put inside a 15 inch wheel.I am also sorting out the front suspension,as pictured the car is sitting on 9 1/2'' tall 1200lb coils.I'm trying to come up with a way to hold them in the car without using tethers.But if I can't come up with a simple solution,tethers  it is. I have to notch the frame for the strut rod travel and do upper ball joint correction. Might do a wedge kit before I cut and reweld the ball joint at a different angle.I won't be using the stock shock mounts as they would go through the top of the hood. So I have a new set of stock 70 shocks coming so I can cut the tops of the make screw on mounts for the Koni's. Yes that is the ride height. There will also be very minimal flaring of the front fenders. Yes,It's rather extreme,but that's my style.This is the craziest Mustang that I could build.

Hello,You know building a car is nothing but moving from one catastrophe to another.Well the front suspension is no different. We all love low cars. and mine will be ,well........ridiculously low,and so creates a whole new set of battles to win. First is the upper ball joint.The upper joint was almost maxed out of its travel with car sitting as it does,which will equal just broken ball joints right out of the box.There are 2 solutions.1 being to use a wedge kit for correction,which I did think about for almost a whole day.Or 2 Just cut the end of the control arm and then bend down at the flange that the ball joint bolts to down 20 degrees. I chose to cut and weld,which is let's be honest,usually my first go to anyway. The pics should show how I did it,Pretty simple really.If ya'll want a more detailed explanation of what is going on I can go into a lot more detail. Also try as I might,I just can't use the stock front upper shock mounts.I would have to cut a holes in the hood to make it work.So I modified a set of mounts from a 70 and will be using those.

That looks great Chris. Is the shed in the background where you've been doing all the work?

Thank you....and yes it is. That's the biggest structure that I could fit with the septic system, road and creek and set backs the township wanted. I also built the wheelstander in there.
