Should I stick with the GW arms in the back, replace the pumpkin bushings with new rubber, and to del-a-lum up front?
That is what I could do in that situation, if the bushings in the pumpkin are worn out (mine were in surprisingly good shape when I pulled them out last year). Might consider getting a NEW pair of stock uppers while you are in there, they do wear out and a pair of new uppers is only about $65 from Dal.
Replace the arms (which are $65/pair), and inspect the bushings in the axle. The bushings in the axle are a bear to remove if you don't have the right tool (I see that someone "bumped" my thread about the right tool today.....costs $80 but literally saves HOURS of work).
