1. Buy Totaled ZJ
2. Remove 318 from ZJ
3. Put said 318 in Comanche
4. ????
5. Drive MJ everywhere.
Personally, Thats what i would do. Granted my MJ is an 86 so ther 4.0 doesnt quite fit right, but with the 318 you gain power, lose weight. Plus you can then part out/scrap remaining ZJ parts, and use the money to go towards a lift, tires, etc. And, as a bonus, several ZJ steering components will go on the MJ and beef it up a bit.
