70 Longhorn C 20 update w questions

[G-749]

Hello all,
Finally got pittman arm off. Which brand should I buy to replace, or get from Classic Industries? Steering column is on order from forum member to replace trashed column.
Couldn't pass on deal from FB market place,4 235 x 85 x 16 BFG AT on Ford accuride rims ,currently mounted white letter out. Still have on truck 4 , 235 x 85 x16 Uniroyal Laredo M+S 75 % on 16 inch Chevy rims, also have unknown spare under truck and one , 3 PC chevy 16 rim with dry rotted Uniroyal on it.
Truck has had front disc brakes added by PO and 700 r4 tranny. Does anyone see any problem with running the BFGs on the Ford rims on the front end, read on herear in search to put spacers on rear wheels to make track width of front and rear wheels be close to each other.? SPID was scraped off, so what should a 70 longhorn with dual battery, dealer installed air,gages, orange custom interior and rear bumper, front sway bar. Truck repainted red outside,interior is original orange paint, and all trim holes filled. 3 photos I got with truck show white upper cab and the upper andlower exterior chrome straps, now missing.
Anybody Anywhere have Anything about the dealer installed factory air, interior box is broken. Newbie questions. TIA and good luck on all your projects.
