RE: GROUP BUILD - Top Flite Giant Scale F4U Corsair
The nylon tube was just a temporary fix until I worked all the bugs out. A friend of mine is silver soldering a brass tube onto a brass plate to mount on the back of the door. I'll post pics when possible. The strap is bolted on with a 2-56 x 1/2" bolt going through the front tabs, it has a 1/8" tube cut 3/16" long placed between the two tabs. This keeps the tabs separated allowing room to mount the ball links on each side.
Hope this crude drawing helps.
