There's even odds that a local source with lower cost and margins would source it from the exact same maker as McMaster-Carr and sell it significantly cheaper.

I understand where you're coming from Ken, and believe me you are correct.

The problem lies in the fact the drawing states specifically a McMaster Carr P/N.

Should I venture off in another direction to make more profit and for whatever reason am being asked to provide proof of material source, I'd be screwed.

I recommend you find an alternative source then contact your customer and offer a price reduction of one half of the difference in price.  That way both sides would be happy.
