Your top 5 7123 improvements

Hey folks!


I’m curious what you consider to be the best 5 upgrades to our cars. Could be for better drivability, performance, safety etc.


Let’s hear it! :-)

The top 5 mods for my car are:


1. Adding the coupe winder mechanisms to the fastback so the rear quarter windows roll down.

2. A small subtle reverse camera mounted near the passenger sun-visor that points back to the passenger side blind spot (way less stress when changing lanes or merging in a right hand drive country)

3. Replaced upper control arms with mid-1970's to mid-1980's Australian Ford Falcon control arms, these are exactly the same configuration as Mustang control arms but have rubber bushes rather than the Mustang metal on metal standard variety, so a softer ride and no more squeaking.

4. Disc brake conversion kit (got them, but not yet installed)

5. Plasma tail light globes that doubled the brake and blinker light output.

1. Upgrade from FMX to Modern 5 Speed. Makes for an entirely different car and driving experience.

2. Upgrade front disc breaks to larger willwood set up. Really brings the car to a stop quickly.

3. Replace entire front suspension with new moog components including boxing in the lower control arms, a much larger anti-sway bar, and heavier 1” lowering springs. The car handles 100x better.

4. Upgrade my steering box to a quick ratio box.

5. Engine and rear end upgrades. Aussie 2v heads, cam, intake, etc and 3.70 locker rearend.

73 Grande H Code. Headman long tube headers, T-5 Transmission, 3.70 Traclok, Lowered 1" all around, Aussie 2v heads w/ 2.19 intake, 1.71 exhaust, screw in studs, full roller cam 608/612 lift 280/281 duration LSA 112, Quick Fuel 750 CFM double pumper, AirGap intake.

Hard to boil it down to five:

- Stroker to 408 with all the new engine components.

- TBI fuel injection.

- New front end components (OEMish).

- TKO600 5-speed trans.

- Exhaust cutoffs.


Close to the top five: brake upgrade to four new discs. Carrara steering wheel. TMI seat covers and foam.

Upcoming that may make the list:

Rear end upgrade to Truetrack. Brake master cylinder upgrade and vacuum pump system.

1971 M-Code Mach 1 w/Ram Air, 408 stroker, 285/291 0.558" roller cam, Blue Thunder intake, TKO600, Hooker headers with electric cut-offs, FiTech EFI w/ RobBMC PowerSurge pump

Strange center section with Truetrac, 3.5 gear and 31 spline axles, 4-wheel disc brakes

393 Stroker motor with lots of goodies including electronic ignition


heavy duty yokes and 1350 u-joints throughout the driveline


Added Air conditioning


Lowered front and rear along with the addition of welded in subframe connectors


changed gear to a 3.89 31 spline unit with heavy duty replacement axles



While this is really a lot more than 5 items, it is the 5 areas that I feel added the most to the car- I did not mention the rear disc brakes, the 17" wheels, the drag radials, the 6 point roll cage, the relocated battery, the 1` wire 135 amp alternator, the custom interior panels aluminum seats and seat braces with full harnesses . . .



"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

::thumb:: ::thumb:: ::thumb::  Vinnie, I like this thread to know everyone's improvements and yet remain as original as possible.  ::thumb:: ::thumb:: ::thumb::



What I self added also when rebuild the Mustang:


- under dash lights under the front seat's for floorlight rear passenger;

- electric trunk release

- mounted sound speakers L+R under the dashboard (room enough for that, no speakers in the doors or kickpanels)

- extra sigar lighter socket in mid.console(shifter) for navigation or cell phone USB loading or ...

- recent convert the original mid.console clock to Quartz 

- replace the shinnie Q-panel ashtray(also Ford but incorrect for Mustang) to original

Besides the obvious rust repair and shiny paint & new suspension.....


1) Cibie/Valeo headlamp housings with H4 lamps and relay pack - it's like driving a new car at night

2) Front footwell courtesy lights - no more black hole

3) Auto -> 4 speed - I hate automatics

4) Urethane sway bar bushings & endlinks

5) Rebuilt variable ratio steering box

My top 5 and why:


1 - Adding subframe connectors - Made the car feel much more solid

2 - Swapping from a C-6 to a T-5 manual transmission - It drives like a completely different car

3 - Installing larger sway bars and high pressure gas shocks - The car is much more stable and driveable… a GREAT road car

4 - Converting to 18" wheels and tires - Coupled with the shocks and sway bars the car feels much more stable and controlable

5 - Converting the dash lights to LED and replacing the clear lens - It makes the dash much more visible day and night

5a - LOL! I added a convex lens to the passenger side mirror - I can actually SEE things!


There are quite a few other little things that have made a difference and many others planned to improve the driving experience.

Always so many projects going hard to choose.


1:   Remove tail lights, blast the inside with walnut shells to remove chalk and paint with Krylon Fusion paint. Polish frame and get rid of the factory foam seals and replace with Daniel Carpenter seals. Appy POR on the inside gasket area of the tail light panel. Use 3-M strip calk to keep water out of the seam. 


2:   Restore long console and install.


3:   Install new convertible top.


4:   Install Ultra High Strength Steel 8 point roll cage in vert.


5:   Beef up suspension and chassis using Ultra High Strength Steel.

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

I have to pick 5? when I bought my 73 Mex Mach 1 last year, it was basically a survivor, that had just barely survived. no rust, but almost no maintenance. pretty much the car was unsafe at any speed including parked. my first repairs were things that were Major issues: blew a hole in the timing cover and lost all coolant. but then I started on suspension, driveline and steering. that got the car safe. next I did crate motor, suspension( again) exhaust etc. now I have a safe, fun, dependable car. but the Next 5 things, that is the question: Next

1. Wiring harness


3. weather stripping

4. seats( got to do something about the vinyl...too sweaty)....possibly replace vinyl with something else but keep stock seats

5. blast and paint undercarriage. there is no rot, but there is some surface rust.

1. Repaint car to Factory new

2. Restore entire interior to Factory new

3. Rebuild engine stock, reliability upgrades

4. Rebuild trans with re-programming

5. Drive for 30 years, resisting any urges to have car look like I ran through Pep Boys with a magnet!

( Although, I must admit, many, many times, I've thought of stuff like aftermarket wheels, highly modified engine, and such, but in all the years I've had it as an everyday driver, it's never let me down, so I think I'll keep it just like it is. )
