My Blazer had a Pete Jackson Gear Drive on it when purchased but since the block was cracked I ended up building another 350. I would like to transfer the gear drive to the new motor. I think I may have lost some of the parts. It appears that the bolts holding the gear to the cam require bushings to center the gear(Holes in the gear are way to big for the bolts). Am I correct about this? I have the bushing for the cam pin but not the bolts. Am I missing something? Also does anybody have the install sheet that comes with the gear drive? Thanks.
