go with the block from a 3.4L camaro/firebird. it's identical on the outside and will accept all your current accessories/intake/exhaust.

the front brakes changed. you'll need to keep the different eras together as a set. be sure to cap the vaccum source for the old front axle. Other than that, the front should go right in. :thumbsup:

Given identical drivetrains, the longbed MJ will have a driveshaft 6" longer than a shortbed MJ.
If you have a 4.0L auto, you can get a driveshaft from a 4.0L stick and it'll be 1" longer.
You need the proper bellhousing and the slave componants (slave, shifter fork, throughout bearing). Try to make sure they are all there when you buy the bellhousing.
