Thanks, guys. Picked it up in San Mateo, just south of San Francisco. So far I just have temp tags, but no problems with registration just yet.

It's not perfect, but probably the best option. We stopped by the guy's place to pick it up and install it. Seeing he fabbed it himself, I wanted to ensure it went together as advertised. He lived an hour off our regular route, so I figured it was worth it. Nice driving side roads through zinfandel country, too.
