Brake fitment. Will '89 200FWD calipers fit a 90 20vQ?

[john at westcoastgarage.net]

This went to the 20v list, but replies are scant.  Maybe this is a 
better venue.  I  am parting an 89 200 FWD.  Can the calipers from this 
car be easily adapted for use on my 20v sedan?  My rotors are 250K old 
and should probably replaced at the next pad change, and as you know, 
they're more than a bit pricey.  If these calipers will fit, and I can 
use a less obscure rotor, I would be mighty happy!  TIA, John
