z32 calipers form Checkers

[hulkster_s13]

just was wondering if any of you guys came across this. I picked up some refurbished calipers from checkers, i stripped out the brakeline threads on my z32 30mm calipers. so i needed new ones. My local machine shop said they couldn't repair it. But when i got them they had a spacer in between them. i am just curious if anyone has come across this before.I've never seen this before.
