grill mounting hole repair.......
 

i had some busted off mounting bolts for the grills on my 75 t\a. to get them out i drilled out the plastic around the bolt to get them out. i need to fill the holes with some type of epoxy filler and redrill the holes. was thinking jb weld , but it does not adhere well to some types of plastic per their website. any recomendations on a product to use ?
