This chart may help with what you need. Looks like 51.4" to the housing flange? http://www.mymopar.com/forum_images/rearaxledims.jpg

GAWD!!! I wish someone would outlaw that chart, it's everywhere and mostly wrong.

All '66-'72 A-body housings are 52 5/8" wide. Using the BBP axles in an A-body housing will increase the overall width 5/8" so, to keep the original overall width, you'd have to make the housing 52.0".

John , thank you. What is it about the BBP axles that make it 5/8" wider?

Total brake offset for '65 and newer 5 x 4.5" Mopar axles measures 2.525" when installed. The 5 x 4" version measures 2.25".

Thank you Dr. Diff.

Not to rob Cass of any business, but I would respline a set of C body axle shafts just like I would bore and reuse a 40-50 year old engine block or crank. Why? It's cheap and more importantly I'M CHEAP!!! An hour of shop time compared to brand new shafts? Unless you are going to stand on this car, I don't see any reason not to give grandpa's old axles a new lease on life.

Mopar Action did a great story on this back in the 90's and it's likely available at their website. I got mine out of a 69 Fury. Go for it. If you can't get the thing together, call the Dr.

So, how much does it cost for someone to respline a set of axles? You have to figure in shipping both ways too. Not everyone has someone close by that can/will do it.

Moser in Portland Indiana. $125 (per pair) plus the ride (both ways)

another vote for dr diff
I used to respline them back in the day
cheaper to buy them from the dr and your done with studs & brgs.

If I didn't already have em I would call the Doc

Back in the day when I worked in the wrecking yard we used to mark the end of the aisles with axles that we would pound in the ground and spray paint with fluorescent colors. When we finally closed the yard, we crushed all the cars that were left, pulled the axles out of the ground and sent everything to the scrap mill. The C body axles were a favorite for the task because we had so many of them and they never sold.

You should send that sign over to the parts store post in the general section...

Glad you liked it, feel free to use it when it seems right!!!
