Just a quick note, the Fox platform in the Mustangs ran from 77-93 with the SN95 platform starting in 1995 which ran through 2004 giving way to the S197 platform.
Also, The front LCAs on the 87-88 T-Birds/Cougars are 14" long which is the same as the 95-04 Mustang front LCAs while the 83-86 Birds/Cougars have the 12.75" long front LCA's which are the same as the 79-93 Fox Mustangs/Capris. Call Maximum Motorsports and they will verify this. The 84-86 Mustang SVO utilized the same front LCA's as the 82-83 Lincoln Continental which are entirely different even though they are 14" long. They have a deeper spring pocket, ball joint is raised, sway bar connection point is moved, and a non-serviceable large diameter ball joint. This LCA requires a longer spring due to the deeper spring pocket and the ball joint will not fit a Fox or SN95 spindle. In general they are impossible to find but I thought it would be worth mentioning.
And here is the controller:
Save your $$$ and when you can afford it switch to 5 lug via a 94-98 V6/GT swap utilizing 99-2004 V6/GT front calipers. The gains here are as follows:
Rear disc brakes
Larger front rotors and twin 44mm piston front calipers
The 94-98 V6 and GT rear axles are the exact same axles and will fit your existing 8.8 housing.
Rotor, caliper, and brake pad selection is excellent vs. the Fox garbage
Wheel selection is light years ahead of the Fox vintage stuff
The front wheel bearing hub assembly allow you to swap rotors and not have to mess with the bearings.
If you are willing you can swap the ABS from the Mustang over to your car. I did it on my '93 Coupe and what a difference letting the ABS modulate the brakes in a panic stop versus "I can out brake and ABS system with my foot"...bullshit.
There are several write ups on the SN95 brake swap on here so do a little research. You can have decent brakes with the 11" Fox front rotors and drum brakes out back but if you swap over to the SN95 gear you will notice a HUGE braking improvement. There is physically no way to make a Fox brake system out perform the SN95 brakes, period.
Please post back up as you learn the Holly software. We are going to build a 351W stoker for my dad's project and he wants to go injected by my experience is leading me towards a factory style Fox Mustang injection setup only with the Ford Mustang 8693 MegaSquirt Gen2 Plug and Play with a Painless EFI harness.
Again, that is one sexy motor!!

I have not verified these numbers but this list has been on the Mustang board for years and as far as I know it has been vetted. Would have been great to also have had the new and uninstalled length so you could make a comparison but this is a lot of good info.
With that being said the general rule of thumb is to run the 94-95 spindles on a stock k-member car and the 96+ on tubular k-member cars as most of them are designed for the 96+ spindle geometry. I know the Maximum Motorsports and Griggs Racing units are designed on the 96+ spindles as I have them both. If you are going to run a tubular k-member call the manufacturer and see what they recommend.
I did run the 96+ spindles on my Mustang for several years with the stock k-member and stock LCA’s but I did run a bump steer kit.
My guess is most dampers would want to be setup the same way.
Data on the 1988 TC Dampers:
Excel-G Strut (P/N 235008):
Compressed Length is 13.5625"
Extended Length is 20.5625"
Excel Gas-A-Just Shock (P/N KG5556):
Compressed Length is 14.000"
Extended Length is 23.250"
Data on the 1993 Mustang Cobra Dampers:
Excel-G Strut (P/N 235009):
Compressed Length is 13.1875"
Extended Length is 19.250"
Excel Gas-A-Just Shock (P/N KG5551):
Compressed Length is 12.625"
Extended Length is 20.6875"
From the data above the dimensional differences are as follows:
Extended Height - 20.5625" (TC) vs. 19.250" (Cobra) for a difference of 1.3125"
Compressed Height - 13.5625" (TC) vs. 13.1875" (Cobra) for a difference of 0.375"
Travel - 7" (TC) vs. 6.0625" (Cobra) for a difference of 0.9375"
Extended Height - 23.250 (TC) vs. 20.6875" (Cobra) for a difference of 2.5625"
Compressed Height - 14.000" (TC) vs. 12.625" (Cobra) for a difference of 1.375"
Travel - 9.25" (TC) vs. 8.0625" (Cobra) for a difference of 1.1875"
So they make the KYB AGX struts and shocks as well as the KYB Excel-G shock for the Mustang but I wanted a direct comparison from the Bird to the Mustang so I did not list those lengths. They are a little different but they are expecting a lowered car i.e. performance based.
You can see that the TC shock is 2.5625" longer when extended and 1.375" longer when compressed and has 1.1875" more travel than the Cobra shock. This of course is just the one brand and model of damper and the aftermarket manufacturers will vary from OEM in lengths. This is due to if they already have a shock that is within 0.25" one way or another they are going to use it and just revalve or at least that is what I have been told.
No real conclusion on my end as to how far up you have to move the Mustang shock to get into the "sweet spot" but I do not profess to be a suspension guru and will leave that to Chuck. Maybe he can explain how he came up with the 3" as I am curious.
You will need to get them powder coated or painted.
I believe it is the Mach 1 springs but hit Vinnie up or do a search on springs and then user name Vinnie and you should find a couple threads on this. I have full coil overs so not much help unless you want to go that route. And please don't cheap out on the caster/camber plates and buy the Maximum Motorsport units.
