Other than the bracket for the charcoal canister to mount to, is the general shape/size the same on the 1974, compared to the 1975?
My 75 tank doesn't have a mounting bracket for the canister.
To say it differently, will the 1974, fit into the 1975?
If you use the 75 tank with the expansion tank , filler neck, and cap it will fit.
Late 74 had the steel expansion tank and charcoal canister in the engine compartment.
You will have to adapt one of the vapor lines in the rocker panel to route the expansion tank fumes to the canister in the engine bay.
