My cross member is removable so I had to do the same, but mine has tube from the A Arm mounts going in a 'U' across. Mounts the clip with some stand offs. The lines go on the inside part of the U going around. Used some Speedway Kevlar lines to connect, all -3 stuff. The rear uses the stock location line, same lines, connected to the backbrace. NHRA allows small holes in the chassis for attachment. Riviets, I used structural Cherry MAX's.
Have pics, but the hard drive crashed on the other computer....
