I had a similar problem on my ’57 Fastwin ignition rebuild. I also used the CDI 183-4477 coils with no problem but the rub block on the new BRP 580148 points was shorter than the original points that were in the motor. I don’t recall the measurements I took at the time but when using the new points I could only get a maximum points gap of .018 – see pic enclosed. The older BRP points made in Turkey always worked fine – the newer versions made in Hong Kong are not as good and on my Fastwin project, the BRP points stated Made in USA on the packaging. Too much outsourcing of parts again I guess.
