I am sure one of my distributors is made out of bits of a distributor that came looking like that , it was £20 still because of the word "Bosch" on the side. I think I rebushed the shaft after managing to actually get it out with a drift and a hammer.
The cool guys in the states would rather you bought the likes of https://www.demon-tweeks.com/uk/msd-ignition-digital-6al-ignition-control-with-rev-limiter-2012158/ which does make a bigger difference to the spark, but on the other hand needs a stable source of firing pulses (a good distributor.. ) to get the timing right.
