The 71 K20 didn't come with a big block. I believe it was an option on the C models. Supposedly my perches are for the small block 350. I'm thinking there should be a bushing or something to take up the space around the skinny ass bolt that goes through that hole. The other perch is much worse than the one in the photo. I held the new engine mount up to the old perch and it does seem to fit marginally okay, but it sure leaves a lot of room for slop. I would think the GM engineers would have come up with something a little better. That being said I just finished tearing down my NP205 transfer case and rebuilding it. I'm not sure what planet the guy was from who designed that case but clearly no thought was given to rebuilding it. Thanks, Jack
