this is getting about out of control.
1 i wouldn't be thinking about what parts i could use when someone dies in a wreck or at least not right away
2 i'm not sure how a commander is a dodge
3 roof scheme doesn't matter all roofs are flimsy they don't intend on the vehicle to flip and catch something in mid air dead center
4 i would take a 4.7 over a hemi any day.
5 a wrangler or cj will always be better than wj,xj,kj,zj, etc.... in my opinion
