New to the forum but I need some help. I recently inherited a Harley that has a Suzuki dual disc front end set up on it. Calipers are in rough shape and need a rebuild but I can’t figure out what set up I have to order the right parts.

it is single piston and the only unique numbering seems to say 3/2…

any help figuring out what I have would be greatly appreciated. I’ve attached a couple pictures that might help.
