I just received my front end rebuild kit from Zack Kanter, and I might mention here that I concur with all who say his customer service is above and beyond expectation. Unfortunately, the shafts were on backorder, and my impatience had me get the kit without shafts. The gm front end post by Bill/Navy Lifer lists an upper inner shaft kit
Shaft, upper arm, offset, with bushings (2 per car)
GM 88913896 $33.84
ACD 45J0023 = Moog K6210
but I don't need the bushings, I have them. Does anyone know a p/n for just the shaft?
