I pulled the first 4.0 out of my 86 CJ7 and when I went to replace it with the freshly rebuilt one, the motor mounts will not fit the block. Can someone help me identify the new block and where I might finda set of mounts that will fit?

You had a 4.0 not a 4.2 in your CJ?

It was built with a 4cyl and I swapped in a 4.0 a few years back.
