OK, so here it is. The 80 inner is a 24 spline, not 27 or thirty like the mini stuff. It is however, a lot bigger than the 27 spline stuff. I read the measurements posted up a while back, and the inner is almost the same size as the 30 spline mini stuff. As for length, I compared the shortside FJ80 to a short side mini (couldn't find the longside) and it looks to be 2.5 inches longer. I measured the short side mini at just under 15 3/8" long, and the cruiser inner sat right at 17 7/8" long.
