Needed arco disk caliper

Needed orignal rear disk brake caliper to fit arco bike.

If you need original then I can't help. Hi if you're looking to just get a caliper that would lol work without any mods then the newer ones OldMiniBikes sells is a perfect replacement.

i have tried the universal china replacement and the pucks grip partly on the teeth not on the flat part of the sprocket also the arm didnt clock correctly and starts too low. im capable of fabricating anything but would rather not on an original bike. im thinking the jaws on an original are deeper. but i really dont know.
