Worked for OBS big block
Worked like a charm for big block Chevy into a 1995 C1500 - should work for all OBS big blocks using factory motor mounts. Note that the 4.3 V6 mounts use shorter bolts.

better than ARP's ridiculous prices
To long for sbc mounts, but can add a spacer (7/16 to 1/2" i.d. Tube).

These fit my 85 S10 with the 2.8 V-6 perfectly!
These fit my 85 S10 with the 2.8 V-6 perfectly even though the Amazon Parts Advisor said they will not fit. They do fit, perfectly! Just enough threads to tighten down fully! Yes I was at the last thread, but they work great and it's a nice fit, I even torqued to spec. Thanks once again Dorman! Great value for a really good quality part.
