Do you have a source/part number for the spring pin? I’ll need to order it online for delivery to an APO address.
Hello Deepsea; Haven't talked with you in a while.
If you buy the T-Rex parts, they don't use the rear axle for the rear attachment, so you wouldn't need the pin.
If you just want a pin, I can look for a place to get one.
Ride safe, Ted
Update; Not sure if you're understanding what I use.
Found these at Mcmaster Carr, but unsure which one is appropriate.

Does this info help?
