FINALLY got this **** out. Bit more blowtorch on it and it finally let go. Been dousing this with plusgas every other day for more than a week!
Also broke a g-clamp in half when the leaf pack bolt sheared off when I looked at it, but I got both leaf packs secured better with new bolts, also got some nice big fat washers on there to locate the leaf packs and lowering blocks much better on the rear end. It still can move somewhat but I think to get it spot on I'm going to need to have some new plates welded on the axle. Maybe time to invest in a MIG welder. Hmm.
Also my relined brake shoes arrived
Feeling like I'm going to go the whole hog with new rear wheel cylinders and have my master cylinder resleeved too.
