Oops, my apologies! Sorry about that.

For those curious, the small amount of extra time it took to make the supporting structure for the frame was more than made up for with the reduced complexity of the bumpers themselves. We will likely be doing something similar again next year if the design calls for it.

Just throwing it on the pile. For the last few years, 1675 has been using "locking pins" similar to the "squared retainer" style here, and 2 sets of bumpers. The pins go through 2 angle brackets from the bumper on the top and bottom of the frame and the frame itself. Sometimes it is a tight fit putting them on with components inside the frame but you can always bring the lock in at an angle as opposed to perpendicular.

FYI,

These types of fasteners are used in racing a lot to mount panels. They have better engagement and clamping force over the pin method. Also the hardware can be retained.
