Charcoal canister lowered to fit
Found myself looking for the best location to fit my EVAP canister after installing a Vortech Supercharger and air filter which consumed the space where the stock canister would go.
Given the stringent smog rules in California, I needed the canister very close to the original spot, ability to service it from the engine compartment and pass visible inspection for smog.
Final decision was to create a thin walled tube with partial bottom to hold the canister underneath the air filter leaving the very top valve exposed to attach the vacuum lines and electrical connects.
Bottom of holder has a small opening to drain out any liquids that drop into the hole.
Canister has been rebuilt with new filters and charcoal, before it is dropped into place.
Canister in final resting place.
Air filter box over canister. Can be removed to service canister from inside engine bay.
Visual inspection can still see top of canister and hoses to clamp off for gas tank leak test.
Bottom of welded holder is still well above air dam and should be well protected from road debris.
Overall, I happy with the form, fit and function.

Very elegant solution , I mounted mine in the same area below the drivers side battery tray and just ran the hoses and wires down to it.

Re: Charcoal canister lowered to fit
Sorry, no build thread, just pictures in my profile.
Started out as an engine rebuild, evolved into a full restoration, on body and engine.
Found a CARB approved SC kit, upgraded the plate to 1/2" aluminum, added bypass valve, upgraded the belt tensioner to modern spring loaded tensioner, added oil and Power Steering cooler to front end, spent time to seal up cowl so air is forced through Rad.
The tolerance to fit everything is extremely tight.
