I am trying to avoid pulling the axles out of my daily Driver EB to measure, then re-install, then pull it all apart a week later....

Ordering 31 spline aftermarket axles; can anyone give me the lengths L & R, to give to the manufacturer?

The first one to respond with the right answers wins 1000 shares of Enron/ Firestone/Kmart stock--- your choice!

Thanks!

those were from my curries, a friend with some WH rears said his measured the same. Now that I look at it, I'm not sure why there is the discrepancy between the stock and aftermarket BB rears... I never had the stock axles in my '77 rear and forgot to measure my '74 :(.......

ok- I believe that should say '76-'77 rear BB aftermarket - at some point in there the axles did get a little longer, I know they are on the '77, just not sure where the change was.. I'll try to find out before I edit my above post...
