I have 89 wrangler that has the 4.2 i6 that needs replaced so I went and bought a 74 cj 4.2 i6 and the guy said it will just drop in with no mods. So I started looking at the new motor and the old one and noticed the mounts are completely different and i have no idea how to fix it. Does anyone make an adapter?

You cant take the mounts off of the old motor and put on the new? The holes in the block should be the same even if the mounts are different.
But maybe he sold you a 232 instead of a 258 (4.2L)? That would cause the change, if thats the case. The 232 straight six was a common motor in the mid 70's, much more than the 258. They look close to the same until you tear it apart.

Is there anyway to tell the difference between the 232 and 258? I'm starting to think that's what happened. Do you know if your able to use some part of one on the other, like header?
