Vic, we have run twelve bolts for years with high horsepower engines etc. I set up the gears and have a lot of experience and proper tools to get it done. I machined billet heavy duty caps for the spool bearings,
made my own solid design pinion spacer that used a shim along with front and rear holes to allow gear lube to flow thru machined tubular spacer. The spacer seemed to always show signs of loosness when tore down. MY Fix, pinion has ran five years now with no spacer between the bearings. If you want to try this always use a new G.M.pinion nut with heavy duty loctite, tighten nut to intended pinion preload and let set a day or two before running the car for loctite to harden. I use a 40 inch pound torque wrench to
set the preload, it was designed to set the preload on jet engines and was military surplus when I bought it
Good luck on fixing the problem, Ray
