Canister & Hose clamps

[ODZKing]

Probably should have posted this here istead of the old thread.
I wanted to inquire what clamps the hoses use to the charcoal canister, then got interested and started reading up on what the canister actually does and found some interesting reading.
First ... what are the correct clamps?
Then second, I see 2 listed one with a cap and one with out ... what is the difference there?
Then ... I noticed, mine is completely different than those I have pictures of and even the correct one I just purchased. I have a California emissions car, however there is no differentiation in the parts book for with and without Calif emissions. I'd never put any thought into it and the only reasone I even changed it is because one of the spickets is cracked on mine.  http://www.dodgecharger.com/forum/index.php/topic,70161.msg1270082.html#msg1270082
The one I purchased is 3577595 (first pic) and the one that was on my car also pictured. I can't imagine the PO replacing it with a generic ... unless it was a California mandate thing.  Anyone see one like this? It has 3 spickets and a plugged hole with removable plug and 3 threaded studs.
Any info appreciated, now I am curious!!
