Dovetail plate to suit tube rings

[Rigel003]

I need a Losmandy D style dovetail plate to suit a set of Astro-Tech tube rings I have

and I'm having trouble finding a plate with a matching hole pattern. I bought a Losmandy 13.5" DAP5 after being told it was compatible, but it turned out to have different spacing. Any ideas about other plates or an adapter to make the DAP5 work?

It looks a lot like the same size as the WO plates.

I did the Losmandy D dovetail dance when I bought my WO rings as well, only to find that they didn't fit. The WO rings that I have look identical to yours.

I'm currently using a Losmandy DUPS shorty dovetail with only the middle screw in place for each ring, and I had to go out and purchase some machine screws short enough to thread properly.

It isn't as rigid as it could be with the WO plate; I really should break down and buy one.

Thanks Eric. I should have mentioned that I have had these mounted on a WO dovetail plate in the past and they fit that perfectly, but now I've purchased a beefier mount with a Losmandy D style saddle. I'd prefer to have them screwed on the outside rather than just the middle for more stability.
