I purchased a stainless steel seamless tone that had an OD of 1.000 inch.  I was able to remove the four rivets with a punch.  They are the press fit type like used for putting data plates on starters, generators, etc. what was interesting is one had a small head allowing me to punch it through to the inside, the other one ( on the same end was slightly larger so I punched it out from the inside.  The end pieces are castings and the insides of the "cup"where the rod goes in is very rough.  The original tube is slightly thin and it appears that the end pieces were hammered on, distorting the ends,  then riveted. The whole thing appears to have been rapidly put together without much attention to detail. 
  Anyway, I had to custom taper the ends of the replacement tube with a grinding wheel so they would fit.  I then fitted the ends on and adjusted them, then drilled the holes for the rivets using a 9/64 inch bit, and Ahmed in the rivets.  I was able to reuse the original rivets.  Now to the powder coater.

Ted,

I agree with all you said.  There were very few of these cars produced in the first few years and documentation on those things is sketchy at best.

I once asked Earl Buton a pin stripe question. He basically told me that no one knows the details for certain on the early Plymouth's.

All we can do is the best we can with what information and clues we have about our early Plymouth's.

Is this the bracket?  It was in my box of left over parts from when I purchased the car in 1973.  (It may have been modified at some point with extra holes before I bought the car.)

Thanks!

What holds the tailpipe on?  There appears to be no brackets rear of the muffler.

Will do. I will call Monday.

Looking real good!

No he didn't. It is still available. He wanted a latter models gas gage that is not the same as this one.

It is just shy to 3+1/8 inches on my 4door sedan

One club member I know recommends Bobs Speedometer (bobsspedometer.com).  He does all types of instruments for old cars. Does good work but expensive.
  You might also call Tom Hannaford at Then and Now Automotive Parts. he may be able to refer you to someone. When my speedo broke 15 years ago he referred me to a man in Naples Florida that repaired it for me, it works great now.

Does anyone know if the differentials or transmissions on our Plymouth's have any yellow metals in them?  ( brass, bronze, or copper)

Chet,
I did check Lowes and Home Depot, then searched on-line.  The link you sent  is great!
Thanks!

The pole on my 4 door sedan is bent - was that way when I bought it years ago.  Any ideas on how to repair it would be appreciated.
The pole is thin wall, 1 inch in diameter, rolled, and appears to be riveted on the ends.
Most hardware poles I have looked at have an OD of 1.050 inch, so will not fit.
The rivet it very thin and long, an unusual size.
If I find a pole that is the right diameter, I still need to figure. Out how to rivet ends. I thought about anealing a finishing nail to make the rivet.

Or, I could try to figure out a way to straighten the pole.

If you are pleased with the rebuilders, it would be good if we could list them somewhere on the web site as references.

There is an excellent article on Trico wiper vacuum motors in the January 2017 issue of Skinned Knuckles.
