I'll need some help about the axle I have in one of my cars. I have a '56 Chrysler New Yorker and a '56 Chrysler Windsor and actually I am working in the conversion of the tapered axle rear brake, according to this link: www.crankshaftcoalition.com/wiki/Mopar_Tapered_Axle_Rear_Brake_Conversion. On this article they are talking about the 8.75 axle, which according to my "Chrysler, 1956 Service Manual" is the one that my New Yorker has. My doubt is that every article I have found on the web about the Mopar 8.75 axle, say the first of them were from 1957 cars. Is my "Service Manual" for the 1956 wrong about what axle I have in my car?

Post a picture of the rear end.

If your service manual is a factory issued book, I'd believe that before some articles found on the web. Here is a pic of what most of the axle's diffs look like. You should be able to figure out what you have based on this.

Thank you guys, yes I definitely have the 8 3/4 according to my serv. manual and confirmed with the picture posted by 78D200. Thanks guys.

i think most of you know to NOT EVER use the 7 1/4 rear end. i think the factory stopped making that one, but dont know when.

Can you get a 9 3/4 Dana 60 made by strange?

You can get Danas built by a number of companies , dealing with Cass @ Doctor Diff in Mt is awesome .

I swapped mine out!
Any one need a good used 7 1/4 good for your 6 or lean burn L A SMALL BLOCK it's in good shape.
