1960 C10 Mystery "Blue hole"
On my 1960 C10 283 with 2 speed powerglide that I am restoring, there is a hole in the firewall next to the master cylinder with a light blue plastic "pipe" through it. Inner diameter is 1 and 13/16th inches, outer diameter is 2 inches. Please see photos.
Does anyone know what this is? Is there a plug that is supposed to go in there?

Re: 1960 C10 Mystery "Blue hole"
Looks to me like the hole for a 60-62 clutch master cylinder, if the truck was a manual transmission then I would've been equipped with a different master cylinder, for both the brakes and the clutch. I'm guessing someone swapped to an auto tranny.

Factory auto truck would've had a plug like this

Does anyone know if there is some way to determine what it was originally built with, other than the "Blue hole"?

Re: 1960 C10 Mystery "Blue hole"
The manual two port was not new to our trucks. My 56 Willeys Jeep had one, had to get new one and part # match to 62
