Someone recommend something a few months back, but can't find it. I believe it was a very small company that sells direct. The use will be to support a large soft luggage piece, and be able to keep the seat for passanger. The stock is okay for a very small bag, but will need to have something for a 25-27" duffel style bag. My favorite so far is one from Wunderlich called the Vario, but it's too much $.
I thought about going to a fab shop but want to try to find something readily available.
