Differences in Late '80's/Early 90's MFD Pickups

I recently bought a '91 s-500 without original MFD pickups that I'd like to restore. In my search for period-correct replacements, I have this question? Were the single coil MFD's that were installed in other models of the late '80's/early 90's, such as the SC-3, the same as the ones in used in the S-500? Thanks for any info!

At a certain point SC3/Skyhawk pickups were different (lower output/resistance.) Later on I believe they were all switched to the higher resistance S500 pickups, not sure when but think someone here should know.

Thanks Danley! Anyone else......Bueller.......?

You may want to read this thread. Discussed difference between S-500/Skyhawk/SC-3 (scroll about 1/4 to 1/3 down)
