Anyone know the listed track width for a 1984 Mustang and a 1980 Triumph TR8?

I got an idea.

Please, just the listed factory track width for each car, don't need anything more than that.

I went to double-check my numbers, but boy do a lot of Fox Mustang references go around in circles on the interweb.

Quick Edit: 1983 Mustang GT track width: 56.6" Front /57.0" Rear From here: 1983 Daytona/Camaro/Mustang review

I thought the TR7 was right around 55. Did some digging and found this but it's hard to read: TR7 Specs

Front track: 55.5" Rear Track: 55.3"

Sorry, couldn't find the same sheet for a TR8.

This says the TR8 is the same.

Do they EVER ! ! ! ! ! ! !

I even started checking other forums, Another doomed fellow was asking about track width and ended up with a lengthy answer about axle thicknesses, like this:

"I'll see if I can dig up some widths on the axles. Here is the info I have and hopefully it will help.

1979 and newer Mustang brake facts:

  • 11"and smaller brakes fit under 15"+ wheels, 12" brakes require 16"+ wheels, and 13"+ brakes require a 17" or larger diameter wheels

  • 1994-1998 Mustang rear axles are 3/4" wider on each side than a 79-93 Mustang.

  • 1999 and newer Mustang rear axles are about 1 7/16" wider on each side than a 79-93 Mustang.

  • 94 and newer Mustang 8.8 will bolt into a 79-93 Mustang but will require brake line adapters.

  • Lincoln Mark7 LSC, SVO Mustang and Fox Body Saleens use a rear axle that is 1.25" wider per side than the 87-93 Mustangs.

  • 94-95 spindles share the same track width as 79-93 spindles.

  • 96 and up spindles have an 8mm wider track width.

  • 79-93 Mustangs all use 9" drums with 7.5 and 8.8 rear axles.

  • 4.0 liter Rangers use a wider 8.8 rear axle and 10" drums."

MAN ! ! ! That's one big load of ass-emission without a scrap of what I needed to know ! ! !

Thanks for the info guys ! ! !
