Re: 258 swap
I would bet there's a difference between the Chevy four banger and the
American Motors six's frame mounts, and maybe a difference between the Borg
Warner T4 and T5 rear mount: http://www.----------.com/cj7stablizerMount.jpg

This is a good point. I have not looked into this but for a few years
in early 80's Jeep used a GM 151 and it is not same engine as later
AMC 2.5. The AMC 2.5/150 was designed with same bellhousing bolt
pattern as GM 151 but not sure about mount hieght. The 151 has a cross
flow head and AMC 150 has intake and exhaust manifold on same side (it
is based off of a cut down 258 with bore and stroke tweaded too but is
does not share 258's bellhousig bolt pattern)

Hello Mike-
Thanks for your reply. I included an ablum with pictures of the engine
chassis mounts, transmission mount, and a pic of how the engine is
tilted against the firewall. The Dana 300 drainhole does line up in
the skid plate and the Trans mount is in the last set of holes in the
crossmember. I'll need to check the sqareness of the body tub.
In the pics the larger of the two chassis mounts is used on the
passenger side and the smaller mount with the slit is being used on
the driver's side.

If you don't mind taking a picture of your engine chassis mounts and
where they are bolted into the chassis that would be helpful.
Thanks again!

Hello Mike-
Thanks for your reply. I included an ablum with pictures of the engine
chassis mounts, transmission mount, and a pic of how the engine is
tilted against the firewall. The Dana 300 drainhole does line up in
the skid plate and the Trans mount is in the last set of holes in the
crossmember. I'll need to check the sqareness of the body tub.
In the pics the larger of the two chassis mounts is used on the
passenger side and the smaller mount with the slit is being used on
the driver's side.

If you don't mind taking a picture of your engine chassis mounts and
where they are bolted into the chassis that would be helpful.
Thanks again!
