pretty hard to match 1 up unless you have one out
worse scenario is to take 2 out of the other side
but odds are that those studs are the same size right on up through the years
If you have any older Gm psrts around you might be ucky and get a pre computer parts man who would know without having to look at a computer screen. tire shops may sometimes carry a supply of wheel studs if not ask them as they are the ones who more than likely change quite a few and they may have a source.
are the studs on your truck l and r/hand thread?.
