      I'm re-gearing my '86 GMC pickup , and want to go with a limited slip   
   unit . It's a stock 2.73:1 8.5" 10 bolt right now , and there seems to   
   be some confusion as to what will fit .   
      As far as I can determine any 8.5" 10 bolt will fit my differential   
   housing , the only difference being the axle spline count . Everything   
   I've found says I should have 28 splines in the 1986 .   
      Anybody here that can verify ? I'm in no particular hurry , it looks   
   like winter arrived here with a vengeance .
