You could always go to the station and ask them?

One near me doesn't care about race cans, just says as far as I'm concerned you brought it here with the standard on it and fitted the racecan later.

I presume same thing applies with these, it's not like your brakes have no fluid in them.

Yes its quite easy to fit some standard ones, you might have to bodge a bracket, or drill the sides of your tail tidy in front of the plate hanger.
