Yes I meant your Ford diff. I just finished firing up the Mazda. I'm ironing out the bugs now, then I will turn my attention back to the Datsun. The Mazda will be my daily driver, more or less, and the Datsun will be for less civil activities, such as meeting at the local Sonic and seeing if kids in Hondas want to race...legally of course (haha). Right now, I'm struggling trying to get street legal. There's this thing called emissions testing, not quite as California, but a pain nonetheless.
