All you have to do is get a L67 TB, fill the coolant holes, and sand it down flat so it seals right. Since you have a 97, you have a vac controlled tranny (4t60) with 2 vac ports on your TB. Now the L67 TB is only really found with one vac port because it'* on 4t65 cars. So the reason you have to get rid of the canister is because you'll be left with one less vac port on the TB. But if you get a T fitting somehow you can re connect the canister. I'm not running a charcoal canister and i'm not having any problems but it'* emissions equipment and you'll need it to pass inspection.
If you don't get what i'm saying just lemme know i'll try and break it down as much as i can.
