Superior Sump IO390

Hello All,

I am installing a Thunderbolt IO390 in an aircraft I'm building for cross country comfort. Vetterman's tell me that I'll need a Superior Cold Air sump if I want to run mufflers.

Does anyone know if bolt patterns and bore sizes work with Superior's sump, an FM200 servo, and the IO390?
