Heat Selector Mounting Holes

Guys:

I bought the stainless heat selector valves for my RV-10 from Aircraft Spruce here:
http://www.aircraftspruce.com/catalog/eppages/heaterbypass3.php?clickkey=89272

They're well made of stainless as advertised. The mounting holes however, are about .060" closer together than the mounting holes on my QB firewall. I checked with the Van's supplied AL ones and the holes line up perfectly. I could just file roughly .030 from each hole on the stainless ones and drive on, but at $188.00 for the pair, I think I'll be calling Spruce for another pair. The question I have for the group is has anyone else seen this with this product? TIA for any info.

I didn't experience that with my standard build. I also purchased mine directly from the manufacturer. I can't tell if ACS uses the same source.
