Hey Carl
I can tell you how I added more work to my center console install. When I was dealing with the forward flange it seemed the flange may have been bent a tad more than necessary. I allowed the console to sit deeper so that it contacted the tab on the firewall. This effectively leveled out the console a bit more and as a result the adjustable pedals and flap detent brackets sat further down. I then had to grind off about 1/16th inch of the brackets off so that when I pushed the button down on the handles the steel rod would not drag along the bottom of the brackets as I pulled the handle through its travel. In hind sight I should have taken some of the bend out or shimmed between the console flange and it mount tabs on the airframe. Hell, Im not sure now if I could have pushed the console forward or not. I would say try to mate the forward end of the console first maybe. Might have helped me out. All in all mine worked out well in the end.
