looks like a good list. Do the caster mod and move the lower arm forward 3/4" to 1". (3/4" requires less grinding). Max safe block is 2". A-body chevelle springs have the same pigtail, but getting the height right may take some trial and error. I have tried the 250, 275, and 300 lb springs, I like the 275lb'ers the best, but you won't be hauling much with them. Welding in a socket of a weight jack is the smartest thing to do, then you can set the R.H. perfect.
