Default Vapor Canister

On my 75 where did the vapor canister connect to?
Aim is somewhere in the garage, 30 plus years and i cant remember, and i think i want to reconnect it back up.

From the tank to the canister to ? What? Intake somewhere on carb?
Ported? Running a holly/Edelbrock .

going to the same process, swithing over to a Holley emmissions carb.
vapor seperator to frame line
frame line to canister tank port
canister purge port to ported vacuum
canister vent port T'd to the pcv intake
Hope this is correct, I'm talking about a replacement canister with the 3 ports on top.

On the 75 it is down in the left front fender well between the inner fender and the firewall. Way down in that dark hole. Best access is to remove the splash pan at the bottom. I assume it is somewhere similar on a 74.

The charcoal in the can is long ago played out. Unless it has been replaced with the appropriate activated charcoal, it is a totally useless appendix.

What charcoal do you use and where is it available?
