I would never say owning a t-bird is the dark side. They're one of my fave's.
If it were mine and I wanted that stock look, I would install a Pertronix distributor. If your's is still tight, they make a conversion kit that's not too expensive. My dizzy was shot so I chucked it. New was 220.00 at Jegs. Works really well and you can adjust the advance curve nicely. If you really want total stock look you can put on the cap that COLKERR mentioned that has the dwell adjust window, you'll just never use it. Just my opinion, John
BTW, my bride and I started dating in a '66 t-bird
