howdy gmc_shane. i just got got a 1989 chevy full size short frame for about the same price you paid for yours ! we'll get it home this weekend. i haven't seen anyone try to use these frames for an advance design truck,,most frame swaps use the s10 frame or some other front clip. i am not sure what i will do with it yet,, but i was wondering how the cab of your 51 fit on the 88 frame. can you please tell us some more details about your project ? i don't have any ideas about your radiator support. later, garyg.
