Yes mine is single piston. I will have to try to pull it off and see if I can get a part number off of it. Thanks for quick reply.
You have a conversion install and the single piston calipers interchange for about 20 years...'69~'89
There may be a casting number on the caliper body to reference what year it was made and use that as a guide for replacement application.
