OK, got it mostly done. Just need to make the tow point now, drill some holes for running speaker wires, remove and finish welding, and take it to the powdercoater.

Folded down, it has about 2" to the garage door opening:

And in position:

Up with the stock bimini top--still enough room for speaker cans.

On the sides, the lower horizontal tube is oval, the upper one is 1.75" round which will accept the board racks. I'm looking forward to keeping the boards out of the boat next summer.
