Engine Mount Problem

Hey guys,

Im having 2 problems with putting in a new front engine mount and i was wondering if you guys could help since you guys have helped me so much with everything.

the bolt that holds the top of the mount to the engine is really long. it seems to be way too long for my new mount (i bought it at autozone and its made by duralast). after screwing that bolt in half way, the bolt gets extremely hard to turn and eventually i twisted the mount (because i was still trying to screw the long bolt in). any ideas on why this might've happened... ? ...now i gotta go pick up another mount -.-;;;

there are three bolts that holds the bottom of the mount to the subframe. the bolt in the front is done from the bottom and the bolt on the sides are done from the top. my left bolt won't thread into the hole in the subframe (the bolt is fine). does this mean the threads on the subframe are fucked ? do i need a new subframe................. ?

thanks a lot guys,
d

oh and btw, does anyone know of any good brands of mounts ? maybe i should just return this duralast mount and order one online...
