There is a Marelli electronic setup for a 124 OHV engine. I bought one off ebay in Italy for my 1300/124. If I am looking at the right box I have, it says it's for a Spider 2000 and is also marked "SM 800 CX". If you do decide to order one (if you can find one) be aware that there are two different shaft lengths. The wrong part number got sent to me and I had to return it for an exchange with the correct one (was not easy either as the seller did not know english).I have a 124 Special sedan, is there an electronic ignition set up from any Spider that would work for the 1438 push rod engine in my sedan? Just wondering at this point.
