I also “modded” a previous mod. I previously had some 3/8” pins that I was using for FSB quick disconnects. But, to be honest, they sucked. When I tried to use them the strong looking wire retainer thing (see pic) would basically pull off leaving the pin.

So I replaced the pins with these great T-handle quick release pins from Grainger (Fastenal has them too). They work perfectly as long as you only drill a hair over 3/8”. Only possible issue I see with these is the release mechanism becoming a little sticky, but nothing a shot of PB won’t fix. I have the version with 2.5 inches of workable length. After installing them I see that you could definitely get away with the 2.25 inch version 2 inch would likely be just a tad short.

In this last photo it looks like the pin is too close to the CV, but there is no way it will touch. About $50 for two of these pins.
