Those centercaps look sweet! You could look into using 3M's panel adhesive for bonding those pieces together, but it is kind of expensive.
A good shop should be able to weld the few pieces fairly cheap. would look a bit more professional in my opinion.
I didn't think about panel bond, or I would of tried that as it is I have moved pass that and just had the parts welded. The bonded metal would have a cleaner look.
Here is what I have so for. I am tracking down a couple of items to get this finished up, I'm also having a new piece of Lexan cut for the top. This should give an idea for the over all look.
I had a brain fart on my end. I moved the pics to the correct folder after I posted them here, well when that happened it broke the link. They should be showing up now.
Most of the parts have been gathered, holes have been drilled and the insulation has been glued down. Now if I can get my glass guy to cut the lexan square so that I can drill the mounting holes, I will be able to get this all installed.
