Looks like I'll go parabolic as well for mine! Where did you get yours?
ordered them off Paddocks in the UK. Had a friend bring them state side for me. If I had to buy springs here I would look into custom leaf packs like akarover used.
I worked on that stuck bleeder with no luck today, it might be time to get a little drastic (think cutoff wheel and drill) Looks like I am going to have to replace a lot of brake line anyway so I might cut the hard line, then I could remove the brake cylinder and work on that bleeder on the bench.
bought a new shed today, now I can clear out all of my lawn and garden crap to give me some more working space.
Have you tried some heat........Mapp gas?
Yes, heated the bleeder with a propane torch but she wouldn't budge.
I'm starting to wonder how much extra weight I'm caring around in rust and dirt, then the several layers of paint slopped on top of all that.
Couple the new springs with new seats and your spine will soothe your worries with non-jarring back pain of relief.
