I didnt have a problem like that with mine.. dont have the heal guard.. but mine the engin bolts would go on fine had it all bolted down but i got to the left side and the damn thing wouldnt line up with the peg, it was like inch-inch 1/2 off.. got it to go on after i used the jack to lif it. AC's never seem to line up right.. but on my old blaster i had DG and had to use aftermarket bolts, after riding it and hittin jumps the damn bolts snaped in half one side then month later the other.. end'd up welding the shit to the frame..
