Ive done RUF and 63s a few times. Love it. I mixed some F150 leaves in with the 63s last time because if was a heavy third gen runner. I would definently spend the money on axle parts or bumpers or anywhere else than buying springs new from anyone. Ive also mixed ranchos, pro comps, or whatever I had in with Rear springs to make a good front pack. Its fun to play with them and get it to sit where you want. Ive made the mistake of running to few springs up front with no bump stops. That makes for jacked up W springs every time.
