RE: 338245 Dashpot - Need replacement/rebuild information. Can someone please advise current interchange for this dashpot - Rumor has it there is a 60's Pontiac that does the trick functionally, or is there experience to share in rebuilding the diaphragm in the original, and/or a source for a replacement cap? Mine is cracked and I would like to replace the diaphragm or whole unit as you may suggest. Thanks! PS - the current unit (original?) is has a trico cast cover - surely this was not only for Packard? 39-41 Caddy??

What was your solution to your dash pot problem? How does one test the diaphragm? I put vacuum on the vacuum port and no action. How do you take apart. Are diaphragms available?
