Well, this sounds like an ongoing issue. Hope this does not step on any toes.

Don't see a tip regarding adapter plate method. I do see a tip from Stovebolt Engine Company/Langdons and another from Barry Weeks. Very well written.
I hope that Dave can write a tip for his method. No reason not to. He has shared it here already and everyone likes it. His method is cleaner and better for the reasons he describes.

Don't know if Langdons is in business and don't know if Dave's site sells them. The point is that members are buying parts that are wrong. If they don't search Stovebolt they don't know what's out there....or in here......or here within.

Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
