You can replace the rear control arms and use a relocation type mount/arms on the upper arms. It has to relocate at the housing and not the body attachment point though. You can overbore the block, but only within the allowable tolerance by the rules.

Again you really need to get a rule book so you can see what you can and cannot do.

A few of us have used a 5 speed, but the majority run a 4 speed Jerico.
