I have 2-3 different designs that I have in the pipe line, when the pipe stops getting longer every time a job gets crossed of the list I'll have time to play with some tube.
design 1: internal bolt in cage that can be fitted to finished cars with GRP side panels.
design 2: external bolt on cage with side impact bars that requires drilling through the side panels for cars with ali sides.
Also have a few different ideas for top bars including back to back C's. Material will most likly be 40 - 42mm by 2-2.5mm wall in ERW or CDS depending on what you want to spend.
