does any one know where I can find a pair of interior door braces for the mirrors. I have a 84 gmc c-1500. GM list the numbers. but there are not serviced any more. GM has changed her way of disposing of old parts. they destroye them. so if some one is parting a truck out,please look for these braces. they atach to the mirror mout and then run over to the inner door panel. thanks roland
