roadmaster

My idler arm and center link need to be replaced. Shop recommends replacing pitman arm at the same time. I can find a Proforged pitman arm for the Buick Roadmaster, but not for a Cadillac Fleetwood. I like the idea of updating the entire steering system, so I hope we can focus on the part...

I own a 1993 roadmaster base model. I can find passenger side manifolds all day. But no driver side ones. What the hell is going on? Do they not exist or is there another Chevrolet that I can use manifold off. I don't want to play around with fitting headers, unless I know they fit stock. Anyone...
