I have a 1937 Pierce 8. For the third time in 25 years my couplers have failed. I have noticed that the thickness of the coupler should not be much more than 3/16 inch. ( I measured this very carefully with vernier calipers ) The total gap open to both disks being 3/8 in. I was told that the GM power steering disks would fit marvelously. They dont. They are way too thick. What to do? Help!
I can fabricate a hard leather disk out of 10 – 13 ounce grade. That thick ness is about right per disk.
I thought John Cislack has some of those discs.
You might want to contact hims and see.
I bought one for my 31 from John Cislak, I think it was around $20 or so and fit perfectly.
I thought Bob Sands had some also
