I got a chance to practice this evening cutting the fulcrum pin out and using a torch to remove the fulcrum pin bushings on a junk wishbone. Glad I had one to practice on before working on a real set of hopefully still good wishbones. Some thoughts:
1) An Angle Grinder with a cutting wheel makes short work of the fulcrum pin. You can work it into the fulcrum pin cutting through the kingpin using the side of the wishbone as a guide. Use a new grinding wheel as the well used one I started with did not have a large enough diameter to cut all of the way through.
2) Bushings - I got my MAPP Gas Torch out and heated up the bushings. Lots of crud burned off and when carefully scraping around with a screwdriver I was able to see silver solder around the edges of the bushing. I scraped as much away as I could while keeping the torch going strong. As it got to cherry red hot I gave it several smacks with a hammer and the bushing popped right out. Be sure and drive it all the way out while torch is keeping it hot or it will get stuck halfway out as solder cools off.
Tomorrow morning I tackle taking the front end apart on Bugsy. He's already on jackstands, bonnet off, wheels off and ready to go tomorrow morning. I'm hoping I find a nice pair of uncracked wishbones. And non siezed fulcrum pins. The set I took off of a '69 Midget were both siezed, both cracked and really unsafe. I know after seeing these wishbones why that Midget got parked.
