I own a 1970 911 S. The original CD unit has now died.
Are there aftermarket (permatune etc.) units that are 3 prong and will bolt in and give better performance?

I was going to replace it with an original Bosch. Which is the better way?

Replace it with a Bosch unit. If you can find a used unit that will save you a lot of money. I had my Bosch unit dump on me and tried to replace it inexpensively with a perma junk. Save yourself a lot of aggrevation. Don't do it. Stock is best. If you want the gory details on the Perma crap unit e mail me at targa911s@hotmail .com

I agree, I have had two failures of the permatune units on a car that is driven 3500 miles a year. The factory units are much better. I had one factory unit failure because the car was overcharging with a failed Marchal voltage regulator. Check for proper voltage and buy the factory unit, they have a nice buzzzzzz when working and are much more reliable in my experience. I still carry a spare in my car.
