I'm new to the Forum but I'm hoping I can still get my question answered.

I have an 89 Civic Si. I can get stock diameter brake rotors that are slotted and cross-drilled (damn nice looking rotors) but unfortunately only available for a 90-91. For 90-91 the rotors are thicker.

I don't wanna go with stock rotors on my car and I don't wanna pay for an over-size kit. Will the calipers from from a 90 fit on an 89?

The guy at the parts store didn't know cause he'd never tried it and the guy at Honda dealership could only tell me the part numbers.
