Hello all. Had the '63 Mercury back on the road for a bit now. Just to get it rolling, had to use the old intregral pulley dampener on it that was originally on the car. It's pretty rough, so I'd like to get a newer style like a PowerBond and put it on there, which also would work with my newer timing pointer setup. Does anyone know off the top of their head if the two dampener/pulley setups have the same spacing?
