Looking nice there Tatey
with the triangualted plates you mention, i can,t remember which way they are placed but if you wait until you weld in parts D12 then offer up the CP7 plates (triangle plates ) it,ll be easy to see their orientation
I,ve used scaffold tube for my cross brace in the roll bar, not that i,m advocating finding a building site tho
I also did the same as Flyerncle, where as my roll hoop was sunk into CP3 & CP4.
Your chassis is really taking shape, nice one mate
are you fitting an Ali rear tub?
cheers
