need basic rear end info.

Looking for a suitable rear end for a 53 stude coupe. Original was 55.5 inch track width. Am I to assume stock wheels were zero offset, so the hub to hub measurement was 55.5? (rear end under it now measure 60 inches and only a positive offset, front wheel drive style wheel, will fit under there.

Outside to outside of the rear springs is 43 inches. Many listings have rear ends with a 43 inch spring perch measurement, but I thought that was center to center, yes/no?

Prefer a 9 inch ford rear end, but also prefer a 5x4 3/4 bolt pattern to match the front. How big a deal is it to redrill the ford axel hub to the chevy pattern?

If I can't find a 9 in in the right width, How inferior is an 8 in? They seem to be in the mII, pinto, econo boxes/ are they strong enough for a mild 350sbc?

Alternately, does anyone have donor information on chevy 10 bolt rear ends?

Where can I find a list of donors that would have positraction rear ends?

If this info is available in the search function, I couldn't find it.

I would have to do some checking but I think the rear end from an s-10 4x4 would be very close to the right width and it has the right bolt pattern and is good enuff unless you are doing something wild..8.8 from a ford ranger might work as well..

To get a 9' I believe it will take a custom housing and axles to get narrow enough for that car..

http://carnut.com/specs/frear.html this is a chart of common rear end widths..

rear end help

Thanks Sam. I'd seen that list before, but I thought I 'd seen some in the 52 - 53 inch range so I could run some deep dish reverse wheels, or go with adapters to change patterns. Mopar is 5x 4.5 same as ford, right? Don't know anthing about them. Is it a big deal to pull the axels and redrill the pattern?

The S10 4x4 rear sound like a good idea. where can I find hub and perch dimentions?

appreciate the help.

At this point I think it is off to the yard with a tape measure to see just what is what..as far as spring perches those are easy to re-do so I don't even go there..just try and get a rear that is close to the right width,,

Oh one more thing is to measure flange to flange as that is where we commonly measure rear ends..

rear ends.

It always comes down to a tape measure and a yard crawl. s OK, I enjoy it.
Just hoping to narrow it down to which yard I start at. Pick and pull 88 and up, Johns 68 and back, or somewhere in the middle. About that flange to flange thing. Exactly what is the "flange"? I've always measured Hub face to Hub face.
I've also seen backing plate to backing plate which I think is nonsense if they don't list drum widths, etc.
And no one has jumped in with comments on redrilling the bolt pattern on the axel. Seems like a simple answer, or does it get complicated with also drilling the drums?

When I speak of the flange it is the axle flange that I speak of..usually that is also the face of the drum as well..drilling the axle flanges to a different bolt pattern can be done tho there are few shops anymore that will do that.The drums need to be drilled as well..

I use car-part.com quite a bit to see if any of the yards near me have what I am looking for..I find it quite convenient for that..

As far as spring perches are concerned I usually am not lucky enough to find a completely bolt in piece so I wind up having to cut off the old ones and weld on some new ones..Just have to get the pinion angle correct..Ain't rodding fun..?? we would have nothing to do if we did not have to figure stuff out..

I did a car-part search and there are lots of those rears in Texas. If you can use one from a later olds bravada some of those came with a locker or posi..the 4x4 version is supposed to be the 8.5 10 bolt and the 2wd is the 7.5 10bolt so I have been told..
