Intake manifold spacer

[PBR]

I need to know if anyone has a part # for the phenolic spacer that fits between the carb and intake on a '50 ? pan, I've only seen one of these spacers, was this an option or not.

All Pans came with the 27412-48 spacer, or else the mounts won't line up.
I think James is making the best ones (or they plan to, as I was consulted about it last year).
Beware that over-torquing will allow the carb and manifold flanges to distort, as the doubled gaskets are somewhat compressible.
