yea its 4 bolts under the tail its easy takes you like 5 mins... as for the holes ive been toying with the notion of building some lil fiberglass nubs jsut like an inch high that would kinda look like the pillers on the stock wing jsut not nearly as tall
shouldn't be too hard but i just havn't had time with finals being this week
or you can weld and fill them up nd get it re painted
