Most of the metal reproduction parts I have bought from various vendors often appear to be fabricated from the same shop. I have gotten some items that even had a competitors stock numbers on them. Case in point, several months ago I looked for door stays and none of the vendors had them in stock. Recently I got a call from a vendor indicating that the part is back in stock, and now all of the retailers have them.
I would call to get them to measure for you before "shooting in the dark" I have an original link or two that I could provide measurements for you if yours are too far gone to be used as templates.
