I have 71 with a mechanical drive for the tach, and single points. Can I get a conversion to transistor type of ignition? I would prefer to keep my own distributor, and just install conversion into distributor with maybe a module and coil change.
There are few conversions availible for the stock tach drive distributor, I used the Mallory Unilite for several trouble free years. You can get them from Summit or Jegs etc.
I installed two different petronix conversions and both failed. I went back to points set up properly and a good dist curve. I use the Mallory 102 points and set the dwell at 30 degrees. With the proper timing and the dist. set up correctly, it runs very well. I did could not tell any difference between the petronix or the points. I know that I can trust the points.

I too went with the original Petronix. I didn't care for it, and the way it was on under the dist cap...I was always afraid it would give out on me. It didn't but I decided to order a Mallary Unilite Billet Tach Drive Dist and go that route. Of course its a lot more expensive, but now I feel I have worry free operation (Knock on wood). I haven't heard much about the Petronix II sys...but have heard some people have good luck with the mallory conversion...its been around a long time.
