SOLD-1112016 GS 455 Distributor. 9L 4 restamp, rebuilt. New bushings, gear, points, weights, springs, wires. $400.00 + SH from MA, I see Korrie is looking for one, I'll give him first shot, don't know if he's interested in a restamp.
The part number is not removed they use a new never stamped distributor base. There's a lot more to a stage one distributor then just a part number. Years ago there was a board member who was Restamping distributors I do believe he's not on the board anymore or has retired.

This distributor is not a restamp per se. It was a new blank dist. that was stamped once and only only once.
