Was told it was required when we had the cage certified in the 85, and they'll tag you for a window net as well (and a chute, but probably won't hit you as hard..although with those rear drum brakes you might need it...
I'd double check in a recent rulebook though.

As for the license, not a hard thing to get or a bad thing to have. They probably won't say much to you at BMP since you know them so well, but enough 9 second passes and I would imagine they'd ask.

Looks clean Scott.
