170 ignition parts info needed

Point type ignitions work extremely well and are very reliable if they are taken good care of and maintained properly...

RRR, every time the subject of electronic ignition comes up, you are touting keeping the original points ignition. While I agree with you in theory, (points worked just fine for 70+ years) there are some things we need to consider:

1 - Points ignition went away in the 70's (almost 50 years ago!)
2- Today's points are crap compared to what we could buy just 15 years ago (when I was driving my last points-ignition vehicle.) I have to adjust the points in my wagon about every 1000 miles due to wear. Points used to last far longer in the "old days," I could go 3,000 miles between adjustments, probably longer, I would just check and adjust when I changed the oil.
3 - When I was in trade school (1995) we were told by our instructors that points were obsolete and not to waste time learning about them.

I was taught by my dad and then my high school shop teacher how to properly set up a points ignition. This education was reinforced by working in a restoration/service shop where I was doing tune-ups on points-equipped cars on a weekly, if not daily, basis for a few years.

I am assuming the OP is about my age (mid 40's), and I would be willing to bet that he has never set up a points ignition. I could be wrong about him specifically, but I will maintain that bet for anyone my age or younger, and I'll win most of the time.

So while points are relatively easy to set up, when driveability issues pop up that would send you or I directly to the points, the OP may waste a lot of time and money with plugs, wires, etc. before he learns to look at the points first. Electronic ignition is set it and forget it, and potentially easier for someone who didn't grow up dealing with points.
