Next up is fitting the F-684 corner gussets. These 0.063″ plates reinforce lower longerons and bottom engine mount brackets. They turned out to be a pain in the derriere, at least for me. Because the gusset attaches to the longeron, firewall and bracket at different angles, a lot of finagling was required to make them fit properly. Here’s a crappy pic of the the first one trimmed and being fitted.

There was no way I could make 2D edge distance on the rear-most gusset holes, so I actually ended up discarding the precut parts and making replacements out of shop stock. Here are the finished gussets.

Big thanks go out to Bruce Swayze for help in braining out how to fit these parts. Cheers, Bruce…I owe you a beer!
