Looking good!! You are making great progress. Anxious to see how all the periphery's (HVAC, wipers, electrical, etc ) are all going to go in. Since I have reverse mounted ( under the dash ) dual Wilwood masters, space went from tight to TIGHT between the dash and firewall on my build. I went with the smallest Vintage air unit available. Still ate up the entire right side of the under dash area. Ducting for 3 levels of heat ( defrost, mid, floor) also killed lots of space. Wiper system sits directly in front of the heater box. If I had to do it again, don't think I would have installed a wiper system. Rain-X just works too good! I did split up my electrical system. My battery and controls for the power door locks and windows are located behind the seat with access doors in the trunk front wall. Main fuse panel is located in the center area under the dash in a swing down panel ( that don't swing down much anymore) for easy access - NOT!
