be careful with those LED light strips. I have been messing around with some and ones that say they are waterproof are not. If these have the sticky back to them that will be an issue during the summer time. I have had several fall off my 4runner. I have that piece off now and i am working on some holders to replace the stock ones for led lights. As mine are really rusted out.
If you need someone to weld your design up I know a bunch of people that do that stuff where I live. (NC coast) These guys build custom aluminum t-tops for boats.
