Front end rebuild....buy new or rebuild?

What are problem solver bushings? Should I be using those? I just got a stock rebuild from ESPO. Are the hotchkiss shocks worth it if I’m sticking with.87 T bars for now?
moog K7103, it's an offset bushing that enables more caster with the factory parts. i consider them to be essential when rebuilding front suspension. highly recommend them.

any investment in better shocks is a good investment. if you plan on going with heavier bars in the future these will compliment them nicely. but if you're looking to save a little money now, they're not strictly necessary-- some off the shelf monroes or whatever will be fine, but they would be a welcome addition to the party.
