I have never seen one run off the distributor as was the case with early corvettes. The first 'vettes also ran off the generator so that is where I'd look. It isn't too likely that you still have the original generator with the tach drive and god help you in finding one. | | | | | Joined: Jul 2007 Posts: 461 Shop Shark | | Shop Shark Joined: Jul 2007 Posts: 461 | Well said by 53moneypit. If you find a cable and drive for the generator setup, you have to make sure the water pump and generator pulley sizes are correct, or the tach won't show the proper engine speed.

I believe Eckler's corvette parts sells a replacement drive kit for those generators for around 150.00 might be worth the search... | | |
