Hey guys! I just replaced the motor mounts on the 351C and "bolts" from were acquired from Johnsmustang.

Of the 4 bolts that screw into the block. 1 bolt would not catch at all if it did. It would spin freely it is the right size because pitch and length match, however when the bolt was being tightened down it just wouldn't securely tighten. so I reverted that 1 screw back to the original and now its not catching. My only guess is that these bolts are supposed to be stretch bolts. can someone please confirm this? If I need to upgrade to I higher grade of bolts, noted, I just need some expert advice to know what may be going on here.
