Lloyd's right.....i've done a couple of those....you'll also need two screws for the "upper" holes in the gripframe( they're different than the ones used on the SBH and you'll need grip panels. Still the best way to go is find a used Bisley Vaquero, buy it, get the parts you need from the Bisley Vaquero, put em in your SBH. Then put the SBH parts in the Vaquero and sell the Vaquero. You can pretty much break even. By the time you Buy a gripframe in the white,buy the other parts you need, finish the gripframe and buy a pair of grips you'll have wellover 200 bucks in it.
