GM 8.5" rear end spline count
Hey guys,
I need to order up a truetrac and new gears. Did our trucks all come with 28 spline count shafts? I had it apart two years ago and I can't remember. I feel like it was 28 spline. I think from 1989 and up is the 30 count spline. Can anyone confirm? I know I'm being lazy by not pulling it apart, but I'm in paint and body work mode now and dont need extra oil around the small garage at this point. Thanks Paul |
