Rolo nonturbo

Ok I own a 83 280ZX and I found out apon a brakejob that the guide pins are stipped. I know that there is 5 junked out Zs that are being parted out 1 of which is a 84-86 300ZX and the other is a 80 280ZXT 2+2 which should I pull the pins out of that will work. I can't just order new ones it takes a decade and two I just don't have $90 laying around. I got a second Question involving interior parts. How well does the carpet of a 300ZX fit into a 280ZX? No worries gents, I've lerked here long enough to download the FSM from Xenon.
