Pivot pin sleeves seized

If any of y’all have been following along on my other thread, you’ll know I’ve been having issues with my dusters front end. Turns out my new poly LCA bushings got ruined by the inner sleeves that were somehow damaged previously. I’m going to replace them with some rubber bushings and was planning on grinding down the inner sleeves to make them smooth again. But they are seized onto the pivot pins for the LCAs. I tried soaking it in PB blaster, heating it up with a torch, using two giant pipe wrenches, but the sleeve will not budge. Should I just try to cut the sleeves off with a dremel? I can’t find any new sleeves anywhere, it seems like new sleeves only come with the poly bushings.
Any recommendations? Should I just get new greasable pins with poly bushings or should I just get some rubber bushings and try to find new sleeves?
