I took the photos of the bike outside and one of the back showing the fender struts.

new photos

I mounted the battery box but it was in the way of the chain. Four new holes fixed that.

What kind of gas cap do I need?

Brake stay

Check out this site and look at this brake stay, it is the nicest one I have ever seen. Check out his post it has other nice items like foot pegs.

Bars

I got my bars and it was a wise choice not to make them. I got them for 6 Road Customs in Nebraska and the welding is insane. It makes my welding look like .... The fender is next. I am make the bungs right now but have to go back to work tomorrow.

battery box

Well I finished the basic battery box. I put angle iron on the outside to break up the flat metal. I am going to attach or make buckles for a leather top. I put rubber mounts inbetween the box an the channel. Hopefully, the battery will fit.
