'67 C10 accelerator pedal rod firewall support???

[FreeRangeChicken]

Greetings all, I'm a noob here. Recently got my '67 C10 stepside and I'm in love.

It seems like there are a lot of sources to buy ALMOST any reproduction part you need. However, I've been searching high and low for an accelerator pedal rod firewall support (circled in the attached drawing) to no avail.

Could someone kindly point me toward a possible source for these source for these?

I've looked at Ecklers, LMC, Classic Industries, and various other places after some extensive Google searches. Can't figure out if no one is making them, or if I just haven't hit the right search term.

Thanks for your help.
