<p style=”text-align: center;”>Hello. I’m new to the Pierce Arrow world. Never dreamed I’d own one. Found her on Facebook in Vancouver, Washington about a month ago. If anyone has a lead on a distributor cap, rotor, and points, I would be very grateful. Thanks.</p>
Mike,
From Service Bulletin 97-5:
1929 points and Rotor
(To: a member with a 1929 Pierce) ’29
The distributor on your 1929 is a Delco-Remy #668-E. Standard Brands
point sets #DR-2437-P and #DR-2236-P will work. Also, Echlin parts,,rotor
#RR-99 and contact assembly #CS 779-A, are designed to interchange.
The Delco-Remy part numbers for the points are: contact arm #813238,
and point #825452.

Mike, David,
Mike, welcome to the world of Pierce Arrow Automobiles!
My 133 does have the Delco 668-E distributor. The points are opposite hand as they ride on opposite sides of the plate. In order to have a 4 lobe cam can produce 8 sparks per distributor shaft revolution, a 45 degree angle between the parts is needed. The points are opposite hand to achieve the proper cam angles; point sets from are NAPA CS779A on the left and CS779A on the right side. The CS779A will fit without modification. The CS778A needs to have its wire contact tab removed to allow connecting to the car’s coil wire. The points mounting plate on the right side is a floating / adjustable unit and needs to set the points to fire 45 degrees apart.
There are timing marks on the flywheel, but mine are not readable. Another method of fining top dead center is to use a plastic drinking straw inserted into the spark plug hole and notice the direction reversible point, which is TDC. This procedure is also good for finding the TDC of the next cylinder of the firing order – which uses the other set of points. I use an ohmmeter to determine the point where the points open. Working on a bench to set up the distributor is far easier than in doing this work in the car. A protractor with a hole at the center point to fit the distributor shaft can be useful to find the 45 degree point. An older distributor machine (Sun or Allen) with a degree wheel is even better.
The rotor appears to be available from Straight-Eight.com. They feature Duesenberg parts, but some do interchange with Pierce.
Search with the Delco-Remy part number: 37598 which is shown in the Pierce Parts Catalog for 1929 I have not needed to purchase a rotor, as my car already has a spare. John Cislak sells copies of the Parts Catalog, a very useful book, as most parts and assemblies are shown.
Download the Owners Manual from the Society’s Owner’s Manual Library. It is also a very valuable source of information on your car.
Looking forward to meeting you directly at a Society function in the future. You can email me if you have more questions. Herb Tull
Sir, I believe that I have a proper distributor cap that you are looking for. can you e-mail a picture of what you need I can then ship to you. no idea what the value is. i am in the roster. thank you larry sorcher
14 years ago, I replaced the points in my ’36 Pierce, my ’47 Cadillac, and my ’58 Cadillac with Pertonix electronic ignition. All my hitchhiking in from closed points, burnt points, etc. ended. My cars start quicker, run better, etc. Some expressed the horrors of non originality. I am not a “wrench” and do not aspire to be one. Problem solved. Give them the distributor number, and they will build you a unit
Tony.. right on
