Just curious.. I have lead on these.. what should I expect to pay? These are off a Jeep Kaiser rated at 1 1/4 ton axles. The front dana 60 is a closed knuckle type .. would I be able to convert to standard steering knuckles w/ Ball joints? And would the rear mount up to my Blazer? I know I'd have to cut and move the spring perches.. Thanks ... need some guru guidance.
