ordered h3 motor mounts from amazon yesterday, got them today with free shipping! Looks factory, but there is a gap/offset on one of the mounting holes. About 1/8" gap on the good one, maybe 3/16" on the offset one..





thinking about ordering two more and returning the worst two..

do they move if you pry on them?

I hate New parts not being perfect

Just put a vice grip on the 'good' one and it closed the gap down.

The 'bad' one has some bends on the side of bracket by the rivets so I want to replace that one rather than screw with opening up the bolt hole.

Just noticed the part numbers, one is a -A and the other -B. Wonder what that's about..

I think I saw a sticky tread about motor mounts. wonder if there's anything in there about it

Are they right/left specific?

Are they AC Delco or GM? I would only use OEM on something that takes so much labor to remove and replace.

Looks like genuine GM..

for the cost of these, I wish there was an aftermarket replacement!
