83-85 CR, XR, XL brake calipers

[LWC82PE]

Any know what the difference is between Hondas front brake calipers 83-85? Perhaps more specifically 83 XL600, 84 XR500 and 84 CR125/250/500.

Thanks

i had 84 and 85 model XR250's back in the day and a bit later 86 CR250 and 85 CR500 (which i still have) i could be wrong but i think they are nearly identical or are in fact identical 2 piston calipers between XR /CR in that era.

does it show as same part number ?

XR/XL has cooling fins and CR does not and i checked piston part numbers and they are different too. Not sure what else there is?
