I recently pulled arear out of my 65 cuda that was not stock. The rear was a solid axle and there is no inspection plate in the back. It has 10 bolts on the front and can get at the gears that way. The only markings I can see on the axle is the letter X. Anybody know what it came from?
The last owner of the cuda said it was from a satallite.

small bolt pattern or big bolt pattern? Also if you measure between the drums and between the spring perches there is a table here:

that will help you id the axle in question.

-Daty

thats an 8 3/4 rear axle

the # for the center is on the side by the pinion

last 3 digets is what you use to referance them

i.e 741,742,489,

open or sure grips

should have a 4.5 wbp

should be for an 65 A-body but the right b-body is a good swap,and prob what ya buddy used,does he know the gear ratio?

look in the archives for the mesurements on the housings

spring perches been moved to make it fit?

A-body should be 43" centers on the perches,but you can make the 44 center bolt up,look to see if they have been cut and rewelded

measure how wide the housing is frome flange to flange without the backing plates

measure the whole thing axle flange to axle flange

if you pull the chunk the yr and gear will be stamped on the ring gear,and you will know if its an open diff or a suregrip

OH! all most forgot...welcome to the board,lots of info here

Its a big bolt pattern. The stock rear was about an inch shorter that the one in the photo. Thanks.

big as in 5 on 4 1/2" wbp not a 5 on 4" A-body wbp..correct?

truck 8 3/4 rear axles have the large 5 on 5 1/2" wbp like ford trucks and the 85 up dodge trucks

I think an early B-body rear is what you have with 44 centers on the spring perches...unless they have been moved

that would bump the wbp up over the a-body 4"wbp

looking at the center section with the yoke in left hand what are the last 3 digets of the # running along the bottom of the pinion?

how long is the housing from backing plate to backing plate?

The X is the giveaway. It is a 741 housing 8 3/4. Had one in my '65 Coronet originally.
