Is it manufactured from die cast aluminum with a configuration similar to the vastly more common GM #3877660?

Hi Joe
It's very much like 3877660 but with out the throttle spring tab.
Thank Tony

That's what I figured. This is one of two thermostat housings that were used in PRODUCTION only for applications not requiring a throttle pull back spring anchor. The other was GM #3972128.

Can you post or e-mail photos of it?
