Since AlterK gets everything out of the way, it pretty much eliminates the reason for fenderwells.
.....With no torsion bars and no steering box in the way they should be fairly easy to fabricate.
Not always true, depending on tube size.
The rack & pinion steering location places the steering linkage right in the way, as usual.
I chose to have the rear tube wrap around the frame for starter access. If it were inside the frame, starter removal/installation would be impossible with the headers in place.
The passenger side is tight, but under chassis headers are very doable on that side.
And anyone who is anal about "equal tube length" headers should forget about having any made for this setup.
These headers are 2 1/4". Only regrets are not using thicker flanges, and maybe should have gone with step headers instead of straight tube. This pic is over 10 years old, and partial inner fenderwells have been installed, brake lines moved, and front end rewired since then.
The more recent pic clearly shows the steering linkage...and Andy's stout plate being mocked up. A steering linkage stabilizer is in the plans.
