Re: Distributor Cap

G'day Mates, sorry for the tardy response but apart from having a bit to do, it's the middle of winter over here and pretty cold in the shed. I don't know what I'm doing wrong but I actually prepared a response and went to upload a photo to it and the lot disappeared into the ether never to be seen again, so I'm trying again and holding my breath at the same time as I not the world's best typist and it takes awhile to write this stuff! This time I might actually submit the text and then edit and try to add the photo later.

OK, I dug out my spare distributor, which is a #1110865 and fitted with twin points (factory setup?) and, to my surprise, is also fitted with my other new spare NAPA #RR158 cap and NAPA #RR159 rotor button (as usual, the grey matter has failed me again). It seems I retained the original cap and rotor button for the replacement distributor in which I fitted the Pertronix kit (the theory being to carry a good distributor in the spares should the electronic one fail).

Anyway, I was able to compare both new NAPA caps, both on and off another distributor in good condition, and I can report they are different. One cap has brass terminals while the other has aluminium, and the inside terminal "tunnels" on the brass cap are wider. The cap that caused me to start this thread is the one with the aluminium terminals and it still has the same rotational problem on this distributor, leading me to the conclusion that the cap is the problem, more specifically probably a manufacturing fault, and unlikely to be the suggestions you all kindly offered.

I think this cap is headed for the bin and I will be looking to replace it, although as I now realise I still have a good spare the situation is not urgent. Owen, the GM caps you mentioned are likely to be my best bet over here so when you have the time, I would greatly appreciate a list of the relevant part numbers. Thanks in advance. Cheers, John

Sorry fellas, I've tried three times to upload this bxxxxy photo of the two caps but can't make it work. It's a JPEG of 1,222 KB's. I'll try a couple of more times.
