Looking for another throttle plate like this,can be with or w/o barrel valve mount. Throttle plates are 2" diameter, and the throat spacing is 4 11/16" on center. Looks like they might bolt up to a Weber 48ida manifold. I think they might be Scat, but if someone could I.D. for sure that would be great.

I think that's super flow. And if you still need one? I have 1.
