Getting ready to start fabricating a frame and I have no restrictions regarding racing classes to consider. The basic plan is a double diamond style set of connectors using the attachment points BMR points out on their web site, a jacking rail welded to both pinch welds under the doors with attachments to the DD, and a tunnelbrace of some sort to tie the two DD's across the center. Chromemoly exclusively to keep the weight penalty at a minimum. 1 1/2-2" square tube.If anyone has any info I might find useful, I would greatly appreciate hearing it.
