Where does this electrical box go?

OK, long time, No report.
At minimum I suggest you google VR128. This will at least provide optimum performance from either of the 2 OEM alternator types without any other mods.

Well, as I (*I think*) mentioned I picked up a resto VR. The Alternator was from AutoZone but they only had a 2 field.

Now, IIRC, I need to ground one of the fields. Ether one IIRC will do. So I made a short jump wire and ended it with a loop connected to the fulcrum bolt for the Alt. that goes into the aluminum head.
This would be a good ground point?
Or the inner fender is better?

Regardless, the dang thing doesn't charge. The Alt. does check Ok. So I picked up another VR, VR 706, from AutoZone. It isn't the VR 128 as suggested I know and it does look a little funny but work it should.
(I hope! LOL!)
