I have finally reproduced the factory Oldsmobile camshaft thrust plate!

After a TON of research into materials, and very extensive testing and study of the original part, I decided to have these run in an expensive heavy duty bearing grade bronze material. I also changed the design a bit, as the factory thrust plate provided a whopping .030" of end play, which I modified in our design down to .010" end play. The OEM version was made out of an annealed steel - Rockwell hardness testing was surprisingly soft at 38. These will fit all standard Oldsmobile engines with any type of camshaft, and every timing chain design I have tested - total control of camshaft end play = no timing light bouncing around, overall smoother engine run as a result. Remember, this is not something I came up with, this is a very rare Oldsmobile "million dollar engineering" part that unfortunately went extinct about 20 years ago that I have now very carefully reproduced. Original part number GM 22527023.
I have eleven of these currently in stock as of this writing, because I haven't had time to even post about them yet, much less market them. Let me know if you are interested - $105 plus UPS ground shipping. If / when these do go into regular production, costs may come down with larger production runs. And yes, the stock non roller oil gallery plugs work just fine to mount it. Private message or e-mail if interested at the e-mail address below. Please don't call the standard Hydratech phone, as Jim is not aware of this product (essentially no idea).
NOTE: WILL NOT FIT THE 403 DUE TO REVISED OIL GALLERY LOCATIONS
