Motor mounts YJ 4.0

[Air Force Fireman]

I'm puttin a 4.0 into my 92 YJ. It had a 2.5. Doing so makes me have to put new perches on for the motor mounts to sit on. I was wondering if anyone has a YJ with a 4.0 that could measure from the front of the frame to each perch and tell me what the measurements are. I know I have to move them only a few inches, but it may be easier if someone could give me some idea. Thanks guys.

I would recomend bolting the tcase/tranny to the skid plate and bolting that to the frame then with your motor bolted to the tranny you will be able to put the mounts in place and not have a problem with them fitting latter.
