Black Cloud Build
Call Jireh. I just completed a FB250 and they let me change just about everything. Richard will send you a catalog and a parts list. It takes some time but I went through the entire parts list and substituted most parts for others, one because I don't like some things that come in the kit and two because I wanted it to be as different from the kit as possible and still get the kit price. Jireh will let you sub, delete, or add anything in their catalog. I did my research and they have the best prices from what I could find.
Good Luck with the build.
