Default Dana diff widths.

hi all, i have a Dana 60 with #603222-1 stamped on the right axle tube. my research tells me it's from a 70-72 B body. will this fit in a 70 E body? if not does anyone know the difference in width dimensions of these two? i went to the diff/axle thread but that info seems to be gone. thanks to anyone who can help me..............djs

#603222-1 is a '71-'72 B-body Dana with 3.54 gears, the '70 is different. The '71-'72 spring perches are 47.3" apart, E-body is 46" so it's not a bolt in without relocating the perchs or springs.

The overall drum-to-drum width of the '71-'72 B-body Dana is 63", the E-body is 61 5/8".

I have an A-body Duster, B-Body Road Runner and an e-body Cuda. Although they appear very simular and make very good references to one another the parts are not bolt on interchangable. From the front suspention/tortion bars thru the drivetrain and rear-end. I guess it makes better business sense not to have things too interchangable. You will sell more parts if not. This is true with today's hot market items. Notice no cell phones chargers work with newer phones? I work in the tech field and these little differences which could be easily standardized but are not, thus makes everything more frustrating. Although I certainly dont complain. It maybe job security!

And for the record. John. You have the most Mopar trivia information I have ever seen. Did you work for Chrysler in the muscle car era? I have multiple Mopars but dont come close to component and number knowledge to have.

No, I'm just an "information freak"; I compile and catalog info that interests me. For example, I compiled the data in the Moparts link in LDS3500's post above to correct all of the inaccurate info on the web.

I used to narrow rear ends and re-spline axles so I needed correct info.
