I would honestly take my chances with used oem Bosch stuff, even if I had to clean it up some, just watched one of those "will it start after 30 yrs sitting vids on u-tube" and the guy bought a new distributor, points, condenser and coil, no dice, cleaned the old stuff including points, installed and it fired and ran, well! The quality is just not there, granted it is old-tech, but there is no demand for it anymore, knock offs are just that, knock them off the bench and leave them there. :)
