67-72 full floating axle

[greatwhitenorth]

Any of you old GM guys know if you can swap a detroit outta 67-72 eaton full floater into a 14BFF??

I've been told that it will work, but I need confirmation before I buy anything.

For the locker to fit the spline count and diameter must be the same right? Anyone know what the spline count and diameter of these old eaton axles are?

Thanks for the info.

First off--I don't know. BUT...if what I remember is correct from reading about Brian Waddells sub, it had an eaton with a detroit. I believe the magazine article said it had 1.55 inch shafts, and I seem to remember the axles had a relatively course spline. Judging by that, I would say no, it wont work.

Thanks morphed86K10, I was thinking that the shafts would be larger with a coarser spline count but I wasn't sure..

You never know what fits what when your dealing with GM stuff cause it seems like they tried to make everything fit everything.. Oh well. Guess I gotta keep looking for a deal on a 14FF detroit.

Thanks.

That would be cool if you could do that but I don't know that it would work.The Eaton has a 12.5" ring gear, the 14bFF has a 10.5" ring gear. So the carrier is that much larger.

There are 3 different eaton/corporate axle weight ratings only the #11000 axle was 12.5" ring gear the other 2 were smaller. The spline count was, I believe, 17 maybe 12.

As far as I know, the big eaton rearends had 1.55 inch 16 spline axles and the detroits won't work in a 14 bolt.

Detroits for a 14ff aren't that expensive, they are only around $300.00 new. Why take a chance on used when new ones are that cheap?
