HELP GUYS S13/S14 rear brake fitment

[itsRaine]

Okay so I found that my left rear caliper piston seal has a tear in it. I visited a couple junkyards looking for a replacement, but all I saw was three S13's and only one S14 (with the entire rear suspension taken already, including brakes)... can anyone tell me if S13 rear brake calipers will bolt onto an S14? I can't drive my car at all until I get this fixed and local shops want to charge me $400 to get both rear calipers replaced as a unit (they wont do seals, or only one side). So does anyone know if it'll work!?!?

Also, I'm like 99.9% sure on this, but there were no changes in rear brakes from 1995-1998, right? And does ABS/non ABS matter if you're just replacing the caliper?
