I wonder if you'll be looking at a rewire in the future. My 65 was doing some no start issues periodically and then finally ended up with nada. One of the reasons for the Ron Francis box sitting on the shelf waiting for install.

Important note: I and others have found that attaching the starter wires to this is tedious and difficult if you do it after installing the starter. I had to feed the wires in and attach them by working through my fender access "hole" around the middle of the fenderwell that I believe is there to make factory UCA adjustments. I had to turn the 2 nuts that go on the posts a wee bit at a time.
If you can use one of the "post adapters" that we commonly see, that may help, or just attach the wires before you bolt the starter in.
YES! That's the one!
