Rolling Thunder Keith Do you have an air compressor?? If you do put the caliper half into a vice and blow air into the line hole at LOW PRESSURE with a rubber tip. As the pressure builds up the seal will expand around the cup and slide it in. Put brake fluid on all surfaces. NO GREASE. Once you have one cup in get a small block of wood to hold that cup in and do the other one the same way. You should be able to press the cup all the way into the caliper with 2 hands. If not try a C clamp, it should go in easy if not the seal may have flipped in the caliper. You may need 2 people to do this and do both cups an the same time. Watch your fingers
If not go the local gas station and have them install them. Should take 10 minutes. Good luck Rick Lake
