The motor mount on my '93 LS is broken -- both bolts. Not sure why / how. Anyway, it's the half of the driver's side mount that's bolted to the block -- then the bolts hold it to the round part of the mount, with the bolt through it going to the chassis.

If I'm putting a '98 in, which didn't come with mounts, do I only (hopefully) need the block half? Will the '98 block half mount up to the '93 round half like I'm assuming?
