Tailwheel Mount: I can't tell you how many times I've bolted this in and taken it out. It's in now though. I had to fabricate a shim between F-711 and WD-409, and I thinned it down on one side to account for the slight off drilling of the tailwheel mount, but it all lined up in the end (finally!!!) Note that I primed in the back compartment of the fuse. I figure all the moisture will drain here, so might as well.
