Still trying to get concrete info on the '93 and newer Rangers 8.8 and 7.5 shaft diameters and bearing races.  I'm trying to use an 88 XR7 rear with 5 lug and 10" drum without changin the rest of the braking system(cost savings), and I'm waiting for the snow to melt so I can get to the rear end I have.  Also, I thought it would be nice to get the info for the 86-88 Tbirds/Cougars with the wider housing and 9" drums.  I'm also wondering about any more info on post #21.  A sticky is a sticky, but wouldn't it be better with all of the options included?


Any update on this, Im curious.:beatyoass:

I ended up putting the 8.8 under my Tbird to roll it around the yard.  From info I gathered, the Rangers came with 9x1.75" drums, and 10x2.5" drums.  Axle width was 29.16" on '92 and earlier, and 30.16" on '93-97.  But overall width at 1.5" wider than '92 and earlier.  So .5" is lost in translation somewhere.  I've been looking in the local junkyard off and on for a '90-92 10" drum rear end, but no luck.  Since this Spring, money has been non-existent for buying anything experiment-related for the rear, or anything else for the car for that matter.  (except the K-member I recently got)

Eventually I'll get back on it.

Only if it dosent have ABS. The 89-93 mn12's got a 8.8 track loc IRS if it was equiped with ABS. The 94-97 that had traction control came with a 8.8 open IRS rear. The IRS cariers will work in a solid axle but a carier from a solid axle will not work in a IRS.

I don't know if this fits here but Fox Mustang axles will fit in the 87-88 Turbo Coupe housing no problem.  This will make the rear the same width as the Mustang (flange to flange).  The disc brake mounting brackets can then be moved back to use the stock calipers and rotors no problem.  All you have to do is move the flange from the outside of the flange to the inside by cutting a chuck out so it will slide over the tube.  There also a back brace on the back side that I just cut and left off.  May have to use a washer as a spacer to get it exactly right.  This is what I did to upgrade to 31 spline axles and then I use a F150 posi to make the 31 axles work.

I decided to add alittle bit to this. I will get more exact measurement this next weekend when I pull the rear end apart to get the axle lengths.

1984 or 85 turbo diesel rear end from a mark 7

A=61
B=56 about. This measurement I am not sure of, I didn't have any help to mesure it, and still have not taken it apart. This next weekend I want to pull the axles out and measure them.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

Measure the width of the housing if you would.

I measured mine, and it's wider than 54".  So I assume it's the 56" variety. ('88 XR7 8.8 10" drums)

ok, the housing was 55-5/8  also 55.625.This it the measurement from where the brake backing plate touches, not the end of the tube, end of the tube is 57-3/4 or 57.750. hope this helps

Does anyone know how wide a Mark VII 8.8 housing is? Is it 54" or 56"? I'm going to guess it's 54" instead of 56". 56" would make swapping T-bird/Cougar drums and axles a piece of cake......
