I got my belts off Repco too except the part numbers & sizes they had on their system were all wrong (R34 GTT) My old belts had the actual size written on them once we got them off the car so we just took them down and got the same numbers off them.
I'd really like a set of the B-Pillar carbon fibre moulds for an R34GTT...think they'll be making these again?..or should I say, could you find out if they will?
