Stuck Side Seals...Still

I am doing a rebuild on 1979 rx7 12a and I have been pulling the seals out of the rotors, I made little wedges out of the apex seals springs and got all the side seals out except for 3. I have soaked them in purple power multiple times for a few days at a time and I have let them soak in PB Blaster and they still wont come out. Am I missing something? Or am I just going to have to get a new rotor? Pictures attached


Top ones still stuck on two sides




Other side of same rotor

Try Naval Jelly. Only apply to the seal area and let it soak for a few hours.

Oh, I just looked at the images again and noticed...Have you checked the apex seal groove clearance? Looks way worn to me. Might not be worth removing the side seals.

the second picture appears to be slight damage from removing either the apex seal or corner seal.

a simple trick to fixing that is by putting a solid corner seal in place and a used apex seal in its slot and tapping the corner of the combustion rotor face with a hammer to bring the metal back into place then lightly filing the slot flat.

people already throw away enough good repairable parts, that sort of damage isn't all that uncommon and easy to fix if it isn't simply natural wear.
