The seal and gasket set that I bought for my 1951 Henney-Packard had one gasket that was incorrect but fortunately, long before, I happened to have had some made properly by Olson’s Gaskets so the work wasn’t stopped because of the error. I have a good rapport with Olson’s and generally order through Richard Olson himself! Also the rear stabilizer kit I bought from Merritt was wrong and was actually for the front so I had to order the proper one locally through Napa as it was a common size as it turned out.
