71-72 cause they have disc brakes,5 lug,and most of the time power steering already.But then I have 2 GMC's so the grill isn't that big of a deal:p
I like the 67-68 grilles the best,I am always hoping to latch onto a 67-68 chevy SWB,just can't find one I can't get a hold of yet.Seems like this is GMC country around here
