Bummer, the method I used worked good, but I don't think that I ever mentioned it here. I just mounted the wing to the fuse and slid a spacer in the front of the belly pan. Lined it up and let the epoxy set. It seems to only need a space to the front for clearance.

If I remember correctly, there is about 5/8 of an inch before you get into the top side of the ramp if you want to lower the tank. There is also a spreader on the first former that has to be cut and I would imagine it would have to be replaced in a lower position to hold the tank. The back of the tank will end up sitting on top of the half former that is between F1 and F2.

Nasty small area to work in. Good luck, Joe
