The cap looks like an aftermarket cap and the major issues are as follows. Does it take a flat, spring loaded / sweep-type rotor (the inside of the cap should be smooth)? Second, does it have a notch on the underside to lock it in place on the distributor cap? Additional pics should allow people to judge. The parts, if correct, are interchangeable with a Series 80.
Note that the original caps had a number on each of the spark wire connection to show which wire went to which spark plug. Also, the center wire connection, for the coil wire, is not as tall on the original as on the cap you show.
I hope that this is helpful.
That is certainly true of Arnold!
Al,
To piggyback on Bob’s comments, contact Rhode Island Wiring (RIWire.com) and see what they have for you. They make cloth covered plastic covered wire that is very original looking. THey also make wiring harnesses for most classic cars.
Good luck on the project and I reiterate Bob’s position of keeping it original. You are trusting a good number of essential 80+ year-old systems, so don’t ditch the wiring system, which was probably one of the best made at the time. Remember, it is a Pierce-Arrow. You don’t run that much power through the lines, so don’t get too fancy.

Hello Karl,
The Warwick, Rhode Island Meet runs 8 to 12 July 2014.
See you there with Ms. Mary.
Peter
Oh yeah, the Meet would have been perfect if only Tony didn’t bring his junky old car!
The Meet was GREAT, the participants were BETTER and the scenery was not bad either.
Peter
David,
Good Choice!
Now let’s see how it runs with those plugs.
Peter
Yeah Jak,
It is about time you got it right! 
I guess that they do things differently Down Under in OZ!

As Calvin pointed out,the cars that MAY have problems with low ZDDP are not our Pierce-Arrow cars, but 60s cars with high pressure valve springs and flat tappets. We have lovely, well engineered roller lifters, not push rods, etc. Also, as Calvin pointed out, the jury is out on how much damage the new oils will do to the 60s cars.
You should be fine with whatever top quality oil you put in your top quality car (Pierce-Arrow), and if you are at all concerned, go with the Shell Rotella Diesel, as the specs for diesel engines (oil burners) is much more stringent than for gas burners. There is no need for additives and the big advantage of using Shell Rotella is that you don’t have to worry about whether you using the correct oil.
Shell Rotella oil is a very good oil for our Pierce-Arrow cars, as is Castrol GTX.
In addition, so is any good grade diesel engine oil.
I am sure that other members will also chime in on this matter.
Bravo, Chris! Bravo George!
Best to two Superb Pierce-Arrow Gentlemen.
Peter
WOW!
A lovely style, but it is kind of YELLOW, do you think!
Need sunglasses to look at that puppy.
Hello David,
I ran this ad in the Emporium a few weeks / months ago.
I bought one of the heads for my Series 80 as a spare and it looks good. Note that the head for the Series 80 is essentially the same as for the Series 81. The material cast iron (80), vs. aluminum (late 80, 81) is different and the Series 81 may have had a slightly shaved head for more compression.
However, Call Randy and see what he can do for you.
Best regards,
Peter
A long lost friend is producing aluminum cylinder heads for Series 80 / 81 cars. The price is $2,100.00. He also has heads for 8 & 12 cylinder Pierce-Arrow engines. I assume the quality is excellent and I bought one as a spare. If you have interest, contact him at: randallfreeman@rochester.rr.com or @ 585-943-6596.
Hello Neil,
There is such a bolt being offered on EBAY as I write this message.
The item number is: 281075998091.
It states that it is for a 29 – 30, but it sure looks like what you are looking for and it is now at $10.00 plus $6.95 S&H, with NO BIDDERS.
It is slightly different, but not very much.
I would say it is a deal, considering a machine shop would hit you up for at least $100.
You might want to contact the seller and see if he will end the auction early for a price.
I hope that it will work for you.
Good hunting,
Peter
I sent an email yesterday instructing the OneStopMotors.com Customer Service to remove all reference to the Pierce-Arrow Society from the advertising of the Franken-Pierce.
I did point out that the PAS endorses NOTHING, especially HIGHLY questionable vehicles such as the one they have displayed.
If that does not work, we will loose the castle dogs, err, I mean the Attorneys. 
As of this writing, the Franken-Pierce web listing has not been edited.
Merlin and Jane ROCK! Another great Winter Meet hosted by the Best from Louisiana.
We all had great fun, great food and great Pierce-Arrow cars to view.
Did I forget, great Forestry 101! Lots of trees to see.
Many thanks to you, Merlin & Jane.
Hello Tim,
The Series 80 Coach was the lesser expensive of the two sub-models of the Series 80s. The other is the De Luxe, which sold for a premium of approximately 15%. The most noticeable exterior distinction between the Coach and the De Luxe is that the De Luxe has a radius on the rear perimeter of the rear side window. Also, the rear roof line on the De Luxe has more of a radius than does the Coach. In both cases cited above, the Coach has squared features.
In addition to the features mentioned above, the De Luxe had as superior level of finish on the interior and exterior (mahogany versus painted steel interior window surrounds, paint color availability, etc.). I believe I have seen Coach Series 80s with four (4) lug wheels, were as I have only seen six (6) lugs on De Luxe Series 80s.
Regarding your question on distinctions between the Sedan, Club Brougham, etc., The Sedan and Club Brougham are different body styles, with the Sedan being a four (4) door and the Club Brougham being a two (2) door with large front doors and a generous rear seating section. If it were a smaller rear section, it would be a Coupe.
I believe that the Series 80 offerings in 1926 included the following; 5-passenger two-door Coach (yours), 5-passenger four-door Coach and De Luxe Sedan, 7-passenger four-door Coach and De Luxe Sedan, Coach & De Luxe 7-passenger Enclosed Drive Limousine, De Luxe Touring in 5 & 7 passenger, De Luxe 4-passenger Coupe and De Luxe Runabout. I have not SEEN advertisements for a Series 80 Club Brougham.
I may be wrong on some of this, but I believe that the info is credible. Other members will comment as to its accuracy
Good luck on learning about you fine, Pierce-Arrow.
