By the way, I just bought a new set of 31 spline billet steel axles from Moser for one of my cars. All the 67 - 70 Cougars use identical axle lengths in the 9" and 8 inch rears, in fact the 28 spline 8" axles fit the 9" as well.
Anyway the 31 spline Mosers were $398 including a set of retainers delivered to my door with the bearings installed and studs installed. Took five business days.
I'm considering doing something similar. Moser had one page which requests a variety of axle length measurements. If you have them at the ready, could you post them here? Two more questions, and I promise to stop.
1. Do all 31 spline axles use the big bearings?
2. If I could convert from 28 to 31 spline, would it be a custom order?
Do you have the stock 31 spline axles that you took out for sale ??? Let me know, I am in your neck of the woods and would love to see your fleet when I come over to pick up MY new axles for my Mach 1 CJ project car. LOL [email protected]
Thanks again. That is good info. So, if I understand you correctly, I could use the existing 28-spline axles from my 68, a new housing from a 69-70 and a 28-spline Detroit Locker if I were inclined to find another locker and save the 31-spline for a future project.
