-You'll need front disc brakes, get them on FABO
-The V8 swap can be done with whatever K Member you now have,
http://www.engine-swaps.com/ and sometimes the mounts come up here.
- If you go to an 8 3/4" you'll need a shorter drive shaft cuss the 8 3/4 is meatier out front.
- Your current torsion bars should be replaced with .890" or larger, available in tons of places.
- you should invest in a front sway bar, same as above.
