You can use the other calipers that come off the trucks, I know a guy who did-but they arent finned like ours and iirc he said the pistons are smaller.

FWIW I got some bendix the last time and they are really nice, the stocks I shoulda kept but the core charge was 100 bucks so that made 60 bucks total for me if i sent them off.
