06-21-2026 ATLAS Z UPDATE. I started with installing my side view mirrors, and then poured in the engine oil....then decided it was time to get the R200 differential and swap pieces done and out of the way. I first had to clean up the gasket surfaces, then I installed a factory NISSAN gasket, and then filled it with 75W140 Synthetic gear oil. Then I masked off and painted the rear cover with silver engine block paint and then a coat of clear. Tthe case itself I wire wheeled clean,t hen wiped it down and gave it a coat of clear. After that, I painted up the 280Z mustache bar in gloss black and then after cleaning and wire wheeling it clean, I painted the front differential mount in gloss black as well, and then put all of it in the corner out of the way. Quite a bit of work to get it all ready for install. I will remove my existing R180 diff and then clean up the entire area like this before installing the rear end. I also have some TT3 Techno Toy Tuning axle shafts with the Porsche 930 CV joints to put in. PICS:
