hey ae 2wd gurus

my b4.1 keeps stripping the bukhead (bh) screw holes where the tiny dinky screws that hold the alum bh brace are... i mean, i mount a new bh, run the car a few packs, brace is wobbly and threads are stripped... and no i'm no scharzenegger when tightrening them. Yes i coul hi less stuff (although i'm not the worst....) but theres sthing funny here as this is the 2nd bh that goes to the bin now...

any clue?

thanks all

paul
