71 Mach1(Trans Am) 2" nose drop

That's gonna be way cool rumbling down the street for ice cream! It would be awesome to see at a Pro Touring event too! 

I love this build... great work.

Great work and a lot of work. Cant wait until you are done and report driving it. It would probably be a beast.

The part i didnt follow well was the tower bracing. Was that just reinforcing the walls of the tower or does it also include a cross bar from tower to tower?

Edit: after looking at the pictures again in the computer I see it better that on the phone. What you did was kind of box the opening below the UCA.

Hi ,actually I am deciding what to do about adding a bar in between the towers on top.The Chassis Manual does show how and where to put one...........but on the 70 team cars,they don't have one.the 69 cars have the bar,in 70 they deleted it and went to what you would call an upper frame rail that was built and installed from the top of the cowl under the fender apron just to the front of the shock tower.So what I am doing is trying to think like a Kar Kraft engineer and figure out what and how they would have addressed that area. The 70 and 71 rules stated that no additional bars may be added forward of the fire wall,which is why I believe they went to the doubler and made it look like Ford made it that way.....................................even though I believe the 69 Shelby cars had a 1 1/2 tube that went from the top of the torque box to the shock tower.

I would be interested in seeing what you are talking about the 70 going under the fender apron. My guess is that you won't get too much lateral stiffness that way, but definitely longitudinal stiffness. What about reinforcing the current tower braces. They have a near 45 degrees angle so if they were reinforced it should help adding stiffness without the MC cross bar.

Hi.Just more welding,welding,welding and yes more welding.The good news is the engine crossmember is rock solid.I also replaced the bottom of it do to the fact it was bent, smashed in and ugly.I  have never had one of these cars where it wasn't bent somehow.I used a piece of 1/8'' so now you actually can jack it it up there now.The rest is just pretty much weld every seam within reason.Before you could grab it with your hands and squeeze and watch it flex,now all of that is gone.The last thing to do is make extra bracing for the LCA mount. That will not be like on the 69/70 cars.I have come up with 3 different ways to do it.............I just have to pick the idea that uses the least amount of steel and the shortest bolt length,which is also the most ridged.
