Thanks for the great replies. I have found variances in the motor mounts purchased at Checker Auto Parts. Mainly the bolt holes are different diameters. It certainly doesn't help. I'm not sure if this was an original V-8 truck but the metal brackets appear to bolt up to the stock holes in crossmember and frame. There are no new holes anywhere. Do the six cylinder brackets fit V-8's as well? In brackets; I mean the bent metal brackets that block and motor mounts sit down in to. Thanks!
