Had two productive sessions on weekend. First assembled and put in place the roll cage. Next touched up black paint and attached roof structure. Accessory items were attached to the back of the roof just before that. I also attached engine air intake and couple of pipes underneath it. Next I put fuel lines in place. Then worked on brakes. All 4 corners were done and I proceeded to attach whole engine /gearbox assembly to monocoque. Last items to attach were rear brake cooling ducts and diffusor. And here are photos of intermediate steps and how the chassis looks now.
