Dave,
This wasn't all that bad once I got the rack tipped. That was enough to free up both joints and get the angles where they needed to be.
Charlie,
Nope, any header from an early Camaro or Chevelle will fit great. The mock up pipes are 20 dollar swap meet headers for a '69 Camaro with 2" primaries. I also have a "big" 2 1/8th set I got for 30 bucks but I doubt I need anything that big. 2" primaries should be fine.

I got the support bearing lined up last Thursday. It wasn't difficult. I redrilled the mounting holes in the firewall to the inside by about 5/8th's of an inch and the steering works great!
Really can't see any difference on the outside but you can see the old holes on the interior shots.

Looking a bit from the front.

Inside shot. I am fabbing a backing plate to go in here

Here is the backing plate with all of the holes drilled. The pattern is the white piece and this is what the plate will look like when done.

I am thinking I will add a "top" to the bracket also to triangulate the front to the back.
Thanks for the comments.
