[FC] Wanted 1964 front air vent seal. GM part #386199

[Eric Kirven]

Hello All,
I have a 1964 Greenbrier. I am in the process of putting it back together after paint.I haven't been able to find the seal that seals the air inlet door behind the front grill. In the assembly manual it calls out number 386199.I haven't seen anything that is even close to the correct profile. 
So does anyone have one they would be willing to part with?What are you using to replace the seal? 
Thank you in advance.
Best Regards,
Eric Kirven
