Firewall fitting and modifying flange bearing
I'm mocking up my firewall for the first time today, and noticed that the steering hole is overlapping the chassis tube. I'll have to cutoff part of the flange bearing return to make it fit. I see no problems doing this, but I don't remember reading about this elsewhere.
It's possible that the firewall is in wrong place, but it seems pretty close to correct. I've found firewall center and aligned it with chassis center, and fitted lower panels from there.
I can't move the firewall up to move the hole in relation to the chassis, so the only other solution I can see is to move the hole over and make up a plate to cover anything exposed. Right now I prefer just cutting off part of the flange return.

Install the flange on the engine side of the firewall.

LOL, oh that's funny. Of course! I started out by assuming that it was sandwiching the firewall, i.e. one piece inside and the other outside. But of course that's dumb and wouldn't work! I'll leave this post here for general amusement
Thanks NAZ.

Once installed from engine side, you will still have some tube overlap, but I think you'll find it won't interfere. Mine worked out that way.
