Carb ID- Mikuni

[SIKYSA]

Hey all.
I'm working on two ZX10's (88 - 90, same gen...) and had to order a bank of carbs from the US for one of them. Problem is, the carbs they sent aren't from a ZX10 and they don't fit. It's not worth me posting them back... and if I don't get at least a partial refund I'm sure karma will sort it all out eventually.
Anyway my idea is to sell them on, but I can't do that until I know where they actually came from. Pics are below.
Any help is greatly appreciated!

They're BST"s , looks like an aircooled GSXR/GSX-F spacing........ size around 36mm ?

Awesome! I'll look them up and see if I can find any pics to cross check! How do I check the sizing? (Probably a dumb question... but I'm learning! Bit by bit!)

Measure the inside diameter of the carb on the inlet side

looks alot like my fzr 600 carbs, and the 3HH is a model designation for the fzr 600 aswell
