I could be wrong but I thought that the 454ss rear and the 2wd and 4x4 6 lug 14 bolts were the only 9.5s on these trucks and if you got 8 lug you got a 10.5 weather it is a full float or a semi float dose any one have any thing to confirm this or to prove it incorrect
There is no 10.5" semi-floating axle. The 10.5 is full floating, and the 9.5 is semi-floating. The SS axle is special because it's not an 8-lug... I think they're 5 lugs. (The SS is on the fringes of my knowledge)
