Roger- its been a while since I have logged on...Progress is looking good! This might sound like a lot of work, but you could cut the spring perches off, rotate the axle to the right angle for the driveshaft and then weld the spring perches back on. This is how I did the angle for my 8.8 swap and it worked well.
Hi Kirk, yes that is in the back of my mind as an option. I haven't measured my caster, but my return to center is excellent and I don't have any wondering right now. I wheeled it at Rausch without binding of the front driveshaft ujoints as far as I know, but I did break the driveshaft on a rock. I think I'm just going to leave it alone for now and carry a spare driveshaft since it does seem to be a little on the low side.
