Which part is wrong?

[ca90ss]

Pulled the old engine out in my truck today to drop in the new one and when I went to pull the old one out the motor mounts weren't bolted to the perches. So before dropping the new engine in I bolted the motor mounts to the perches first and when I dropped the new engine into place the bolt holes didn't line up. So now I'm trying to figure out if the perches, mounts or the part bolted to the engine is wrong. The truck is a '64 c10 with a 250. Thanks for the help.
