Seems like the general consensus is GM switched to 28 spline in all 10 bolt 7.500" rear ends. Do y'all agree? I've got a 2000 Sonoma 2WD originally came with the 4 banger. Looking to put a posi in mine as well as 4.10 gears with a rebuild kit. What are y'all running for posi's and gears? What bad have you heard or experienced? It's got a V8 4.8 no worries on spinning 4.10's.
