Dimensions might help, like the outside diameter, the inside diameter, and the hole size. I am not an experton them, but that may help other people assist.Got these plates today and there's no makers ID on the plates. A couple have numbers on them that might help a knowledgeable person know. Number on one plate is 22691, another is 226**. Here's a pic:
That number with the size returned a K&H model plate with a quick search. https://www.practicalmachinist.com/vb/showthread.php?t=242926 might this be the right one?Right you are, Silverhawk. Plates are both 8" in Dia; 3/16" thick; and have a 1 5/8" center hole. Both are machined for either a 2,3,or 4 bolt pattern for mounting. One other plate I got is 9/16" thick, drilled on both sides with a 1 1/16" center hole @ 8.5" Diameter.
The two plates pictured are #'s 22691 and 22694. The larger plate is #'d 125085
Thanks for your response.
