I have just got a 1977 810 datsun wagon (auto) with everything original and working like a month ago for a good price and in fairly good condition for $320. The guy sold it cuse he didn’t use it for about 4years and it was running ruff as hell, but since I have no problem with a fixer upper so I got it . It ends up being that the vacuum advance was unplugged and it needed to be timed so I fixed it and it runs grate .
Well let get to my question, I’m thinking on adding an MSD ignition system and I’m not sure witch model to get, the msd-6200 or the msd-6300. I looked them both up and they both seem to be the same or are their anything else different if so what are they. Witch one do u guys think I should get?
