Rumor has it that if you stick your tongue out and bight it just enough that 3 of the holes will line up In order for the mounts to fit/work, but to be honest the crossmember and frame rail need to have some holes added to them to have them fit as designed. The 67-72 engine mount holes are very close to working and if you use the 3 existing holes methods the mount doesn't lay flat on the crossmsmber, has a very small bind on it, and does not allow for any adjustability of the mount

In this pic you can clearly see where I located the drilled hole in relation to the mount's oblong hole on the lower crossmember when the mount is moved rearward as far as possible."

Have you got a good source for those newer mounts? Any of the usual truck parts vendors?

Will they mount the engine higher than the original position of the small block? I do not have a lot of room to spare with my tremec. I won't even be able to remove it without unbolting my high hump (my transmission does not hang below the frame rails). If it goes much higher it's going to be difficult getting it all back together.
Thanks
