NOS adjacent 3990918 motor mounts 427 396 302 350 Camaro Chevelle
 

Hi Friends,

I have a pair of OTC GM NOS motor / engine mounts available here.

Part number is 3990918, they are in the boxes with the correct bolts and instructions. Washers & nuts MIA long ago; those are easily replaced of course.

I was told these were bought way back in the day for a racecar project, may have been mocked up but were not used in favor of solid mounts.

cast numbers in the rubber are 3968700 black 3962748 dk. / dark green 3962740 gold and 3974735 gold/nut

Both instruction sheets present, boxes worn.

These are genuine - your GM car deserves GM parts as they've always said.

Very usable (near) NOS parts - I say that because there seem to be some witness marks on some of the bolt holes... clearly not run though.

Camaro Chevelle Chevy II / Nova Chevrolet Impala Biscayne Caprice 302 327 350 396 427 1967 1968 1969 left or right hand

Thanks all,
Anthony
