Perfect fit for my 68 GMC C20 with SBC 350. The large lock washer split apart when I torqued down the center bolt but not a problem. Just as nice as the more expensive famous brand we all know. This is not for the C10/C20s that have clamshell type mounts.

These mounts worked for a 1969 C20 with a 396 using the original big block engine mounts. You do need to have an extra large, heavy duty washer, as the hole in the big block perches are large. There was enough adjustment in everything to get it all lined up correctly.This was a bear of a job though! I had to remove the perches and the old mounts to get everything out and replaced. Going back in was much easier than coming out, but not a job I want to do again. These mounts are much easier to bolt in than the original style, as the 3rd, lower bolt isn't buried in the mount.

Fit perfect on the perches and LS adapter plates. Will buy again if I do another LS swap in a C10

Good overall except for the cheep grade 5 bolts included with the mounts .for a aftermarket upgrade they could have at least included heavy duty grade 8 mounting bolts. Guess I have to go to the hardware store for decent bolts

They say they’ll work with a big block motor you have to figure out how to put something to keep the bolt from pulling through your frame towers for the motor I think your junk and will send them back
