Just bought a restoration project, 84 music man Sabre!

Just noticed the pickups on these are different from the pre-eb ones? Is it just the covers themselves? I’ve heard they’re slightly smaller than the standard pickups. I got a wiring project ahead of me, have to reverse the pickup switch bypass someone did and make sure the top pickups still work, but I got a deal! Looking forward to it! Is there anywhere to get replacement mute pads? A new pick guard? Maybe new pickup covers?
