Rookie mistake.....need help

I cut the backs off and pushed them forward. One of the suckier jobs I've done but thanks for all the advice...invaluable. I now have right hand threads. Dreading doing the rear now.
Rears are MUCH easier. Not swedged. Use some penetrating oil. Leave nut on lug flush with top end of lug and hit with a big hammer. They will come right out.
