anyone did rear tailight conversion

any one ever converted a gen 2 to have gen 3 rear? i really like how the rear looks on the gen 3s but hate the front ends just wondering what all i would need my dad owns a body shop and he would help me so i jsut need to know what parts and is shouldnt be to expensive since we are doing it. just figured id ask around before i tear into it

seen pictures and looks terrible IMO…the lights are too round for the square da body. but if you decide to do it good luck and hope it turns out good.

i think it looks nice but dont know how its done…
