Subtle:
If you are using a late-model differential, will you run disk brakes all around, or somehow adapt drums to the '84 rear end? With the performance potential of your 2L, disks would be nice, but you'll need to either find a set of late-model 101 spindles/disks/calipers, or use the adapter sold by Centerline. Plus, you'll probably need a booster with disk brakes.
I put a Denso alternator on my Giulia. Got it from Racecar OE Supply (see item A790 at
