Anyone know what splines were available in what year? I have a couple of '73 diffs in my garage. They have the small uni flanges on them and I want to get a multi-hole flange on a '73 diff so I can stuff one into my '74 Cruiser and use the same large flange d-shafts. I bought a 27 spline multi-hole pinion flange, but I fear that it is not the right one. Can't get the flange off until I pick up a 27mm socket.

Thanks

Ben
