Thanks to everyone for their responses. I got it off!!!!
Heat, hammer, repeat, then while still hot, big pipe wrench. Yes it got chewed up, but the Koni insert has a new one. It looks like it was a bit rusted on the threads.
I just got back from testing it out, awesome!
Now just to get it lowered and put on some new torsion bar bushing. Maybe I won't even need bigger torsions or sways
The adjustables are great, once on firm the front does not move, I can't wait to try on the track.
Thanks for all your help.
