small block motor mount problems

[Omaha68C10]

I finally got around to installing the engine in my 68 C10 and I come to find out the motor mounts I bought from NAPA are allmost a full bolt hole off from lineing up with the hole that goes through the engine stands. I thought maybe there was a right and a left hand side, but they both have the same part #. I replaced a small block for a small block and yes the engine is tight against the bell housing. Did NAPA sell me the wrong ones, or is this a case of trying to make cheap Chinese crap fit on an old truck? Also can anyone recommend mounts that actually fit? Thanks,Jon
