Should be able to find parts here and new for much cheaper.
I bet someone might even trade you a power steering column for your manual.
Are you looking for just the shaft that goes inside column? Or the whole column. To replace just the shaft you have to take column apart.
I think the power steering bracket is same for federal pump 383 B-bodies. I think federal is the OE 383 P/S pump, but I would ask.
P/S brackets are probably available new
P/S pump rebuilt from Rock Auto my guess under $75 shipped
P/S gear core is $50 private party seller. That’s all you are buying from Wildcat.
