Rear end swap question

I was searching Craigslist and stumbled across this. First question is would this work on my 1972 charger factory 8 1/4 318/904 car? Second is this a good price for it?


Will this rear end work in mine?

The housing width will be different for the Charger than the Challenger, but almost anything can be made to work.

Here is an axle chart I copied from moparts. It will give you the deminsions of both axles. You will most likely have to shorten your dive shaft or get a different one.
Housing widths, flange to flange

A BODY
'66-'72= 52 5/8"

B BODY
'62-'63= 53 1/4" (And '64 Max Wedge)
'64 = 55 5/8" (Exc. Max Wedge)
'65-'67= 54 1/4"
'68-'70= 54 15/16"
'71-'74= 57 7/8"
'71-'73 wagon= 59 7/16"

C BODY
'65-'69= 56 3/4"
'70-'71= 57 7/8" (Chrysler & Fury)
'70-'74= 59 7/16" (and '69 wagon)

IMPERIAL
'65-'66= 57"
'67-'69= 57 3/8"
'70-'71= 54 3/4"
'72-'73= 59 5/8"

E BODY
'70-'74= 56 31/64"

A100
'65-'70= 56 3/4"

D100
'65-'71= 58 5/16"
'72-'74= 59 7/16"

Hope this helps you out. Matt

I got to laugh at the 56 31/64" measurement. The factory was doing good to hold tolerance to 1/4" on rear ends lol.

No kidding. I've done alot of comparisons of this chart with actual rear ends. Also with trying to get the fattest, biggest tire on a car. The perches are usually 1/4" one way or the other.

The E-body rearend is a little narrower than the B-Body rear but it will work. The price on that rearend however is high. Most E-Bodies came with 8.75's so the E-Body housings are pretty plentiful and inexpensive as are the 10" brakes. The suregrip center sections run around $350-$400.00 for a good used center section. The housing, axles and brakes aren't worth $300.00.
