Little bit more progress in the last few days. I got the new, correct, ball joints in the LCA and UCAs. Either the order taker or Ridetech accidentally shipped them with 63-70 ball joints and not 71-72, but Ridetech sent me new ones for free.
I also installed the new Redhead steering box (3 turn unit) and reworked the steering shaft and connections.
It was using the stock rag-joint and shaft, but the previous owner had used some sort of coupler, with a small cut shaft going inside the steering column, which according to Ididit is a no-no.
I replaced it with an outer DD coupler, into a collapsable steering shaft (safer in the event of a front-end collision) and then into a u-joint instead of a rag-joint.
I had to cut about 7" off the thick side of the DD shaft to get the fit right, but that was anticipated.
Tomorrow and beyond I tackle the driver side suspension, then finish the steering, new sway bar, bleed the brakes, and get it aligned.
