Shep; Yes my steering arm was threaded.
Sorry, I'm not being clear. There were threads (I think) in the knuckle or hub (not sure what its called) that the bolts have to pass through before screwing in to the new steering arm. The length of the shoulder of the bolts was very important here. The bolts had to pass through that threaded part just right in order to properly seat the new steering arm. This is from memory but I recall this took a few attempts and different bolts.
Craig, I like that set up. I honestly don't think I could fit that that box though. That looks like right where my exhaust manifold lands. I have an old Caddy motor in my truck. I'm not sure but I think my motor my be a bit wider than a SBC.
