Ok i have been reading every thread, i have so much info , but do not know what i'm really looking at.I have a rear end 9", I was told it came out of a lincoln, has rear disc, and coil sring mounts. It doesn't seem to have taperd housing! Ok i measured my 8" diff. flange to flange is 54 3/4. Now this rear end is 58" flange to flange, thats 4" more than whats on, The question i guess is, should i cut the rear end down or do i change wheels with a differant offset? I have some nice wheels for it now but they are the standard size 14".I tryed to put a pic of the car but would not load to show what the looks like.Maybe some one has been here?

I've never done what your looking to do, but I can tell you that I considered a lot of wheels and tires for my '67 and there isn't all that much room under those fenders to work with - you can play with offsets by about +/- a half inch, but I doubt your gonna find two inches on each side with any wheel.

Measure the difference axle flange to axle flange(those sound like housing flange measurements to me) and then make a decision. The late model Mustang wheels have really deep insets, like 6". That is if you like the look of new wheels on older cars. Just me, but I don't.

Personally, I would sell it and look for a different rear end unless it has something special like 31spl axles and a T-Lok. If it has 28spl axles, they cannot be shortened and you'll have buy something in the right length. Obviously the housing will also need leaf spring perches to be welded on.

I'm not a Lincoln expert, but I can't think of any that had coil springs and disc brakes on a 9".

Well by the looks of what i have read, its a 31 spline and has track lock,it came from New Mexico.What i have read all Lincoln's and Mark five came with 9", so just what i read, and the measurements are from flange to flange.AT the backing plates, I do like the old wheel look, i have the bullet mustang wheels on it, or lookalike anyways.I know i would have some mounts to install and perches to put on, fine with that just didn't know about the lack of room with a wheel spacing issue

It didn't come from the factory like that, so unless the previous owner changed out the parts, it'll be an open diff with 28 spline axles. This is easy enough to check though - pull the axles and count the number of splines.

Are you making the power to need 31 splines or just want some extra insurance? You can spend big $$ on a 9", or just spend a little. All depends on your goals for it. Brakes for instance - if it's a Versailles or Monarch rearend, then getting new calipers is no problem (O'Reilly's has them), but you can't get e-brake cables. You can use a Lokar cable for $100+, but would you really want to? Alternately, you could use Explorer brakes, but again more $ to pay out...

I'd take a step back, start with how much $ you got into it, think about what you want to do with it (and how much more $ you're looking to spend), and go from there.

Come to think of it, better measure the wheel bolt pattern, the big Lincolns had a 5 x 5" pattern. So your wheels won't fit if so.

Pull the traction lok pumpkin and sell the rest, then start over. Like D.Hearne said, the wheel pattern WILL be wrong. All those coil spring disc brake rears had 5 X 5" bolt circles. Also, they're all 28 spline. After 1973, Ford didn't put 31 spline axles in ANY car.
