Alternator wiring

Yes, as 67Dart273 shows. Put the hole of each side over the tapped hole of the other. You could use the bolts that come with them, except I recall they are too short. I would take a photo, but didn't find them quickly looking in my box of parts. Once you get it, post a photo of them nestled together and I will confirm if OK.

As I mentioned, I haven't installed the MBRP400100CT diodes in my Valiant yet. I used the smaller diodes (100A?) of my first post in my 65 Dart. I haven't driven that car much yet so don't know if there is a problem with the design, but my ammeter does work and the diodes haven't gotten hot that I can tell. If they were to fail, it would probably be pretty quick. The big ones are safer (less heat) and easier to install at the same cost, but I haven't tested if the ammeter still reads well with them. In theory it should, since they shouldn't conduct hardly any current until the drop across the ammeter exceeds ~0.3 V and mine showed ~0.75 V drop at max current.
