6567GTO thank you for the email address. I can use knowledgeable people if something goes wrong with the upgrade.
The customer service rep in the Netherlands was quite helpful. He gave me a toll free number here in the states. Well, it took three more toll free numbers, but I finally got the man in charge of parts for the old machines. Surprisingly, everything is still available for them - including manuals and upgrade kits. Only problem is nothing is cheap. I ended up ordering out an upgrade module that will allow the machine to work on electronic distributors. But should something go wrong, I'll be needing to get in touch with people that have worked on these machines. If anyone needs the phone number for Sun Distributor Machine parts, let me know.
