What's that? IRS under an old pickup truck!?
****, more Ford parts on a Chevy - FWIW, this is just getting stored in a convenient place for the moment; I need to massage the frame and the cradle to make it look less like an abomination when I fit it in there.
Small damper on, rack in it's final spot, but I have to deal with tierod ends; for the best geometry, they need to mount from the underside. Looking into heavy-duty rod-ends and grade 8 hardware or drilling and reaming the steering arm from the bottom.
Air injection crap cut out and holes welded up. Plenty of room for the steering shaft.
