Question about flipper coil stop sizes vs flipper travel and use for right games.
Looking at PBL site shows 4 different coil stops for Williams.
Looking for info on what stop is what size and amount of flipper travel.
#A-8143 (Stop size is ??) = EM games and SS games from 1969 to 1979 ??
#A-10821 (Stop core size 6mm or 0.236) = 1980 to 1987 ??
#A-12111 (stop core size is 7 mm or 0.275) = Used on Williams/Bally games from 02/1988 to 04/1993.
#A-12390 (stop size is 8mm or 0.314) = Used on all Williams/Bally games from 08/1993 to 06/1999.
I'm assuming A-12390 has the longest stop so gives it the shortest flipper travel.
I am upgrading several older Williams system 4 to 7 games.
Ex: Gorgar, you would use stop #???? to keep original flipper travel. Or Black Knight, What stop should I use.
