Brake pushrod firewall seal

[Leeroy]

Anyone had any luck finding a replacement? Mine no longer seems to be there and it's letting in a bit of 'fresh' air from the engine bay I'd rather it wasn't. I thought about a standard grommet with a hole cut out of it (which I'll do if there's nothing else) but when I did this to the mustang the pushrod would eventually just push the seal out with the brake pedal movement.
I see bronco Tom had a bronco replacement but no idea if it works for a slick.

I just cut a piece of rubber in a rectangle to fit under the booster bolts and punched holes for the mounting bolts and pushrod with an empty .45 shell.

Not a bad thought, but I dont have any empty .45 shells! And the stupid gun laws down this way prevent me getting any
