Preferably not. There will a dual brace up the inside - at this stage 32mm 3mm wall with a 50mm x 5 or so (maybe 8mm) plate top and bottom about 40cm apart - welded into a rectangular arrangement - not individual posts. You cant see it in the pic but there is a 6mm alloy plate incorporated in the coaming under the foam to tap into and I have bolt holes pre drilled in the lower coaming that go right through the original dash as well. I am also considering coming sideways off the internal uprights close to the top - sort of an overhead grab rail and then tying that in through the roof to the front end of the two side rails on top - the other end getting welded to the rocket launcher with a 3rd leg in the middle. Just ideas at this stage. I'll know more once I have talked to Josh again.
