I bit the bullet and took the drivers side header off. I have TTI headers, and they have a rempvable pipe so you don't have to remove the torsion bar. I already had the torsion bars out because I am also replacing the front end (PST Super kit) and installing a disc brake conversion from SSBC. The Brake kit reminded me of my old uncle Ambros who was born with 5 dicks - his pants fit him like a glove : ) The brake kit is awsome and looks cool too. Hope it works as good as it looks. The power steering box is easy to remmove with the header out. I purchased a rebuilt replacement from Parts Source (Canadian Tire) for 217 dollars (after casting returned). I learned from a link from FABO that you can get a firm feel steering set up for zero dollars. Aparently, if you add small shim to the relief valve in the power steering pump, you can drop the pump discharge pressure from 1350 psig to about 850 psig. This will change the steering feel from 1969 to 2010. If I don't like it, I can pop the relief valve, remove the shim, and I am back to 1969. I figure with the firmer feel, KYB shocks, and front discs I should be able to make it around a corner. Taking the header off made it much easier to plumb the new brake lines. If you ever try this, do your self a favour and use the Fed Hill Cunifer Copper/Nickle brake lines - easy to flare and a treat to bend.
