Rob -- that's an old photo.... I was trying to find one that would show the "beam clamps" but that was about the best one I had so used it. The WD clip is long gone! Sold it to some guy in California - even delivered it FREE to him! LOL
I was going to use it in my 69 Camaro Convertbile -- but decided that EVERYONE has one of these belly button cars...

and since I already had the Nomad - I decided that I wanted a "hot rod" -- so switched plans to the '37 Ford. I already have the new chassis for that build.
BTW -- Buying good quality "infrastructure" is what I was discussing in another thread -- LIGHTS are something you're not likely to want to take down to replace with "better ones" sometime down the road -- so might as well invest in the ones that will do the job for many years "NOW" rather than later. Good wiring - good commercial quality outlets - insulation so you can work in "the shed" summer or winter.... those things are important to build in when you're building - so that you can just have fun out their doing car stuff when you're done "building".
