If not go to Kirkham's web page select the S/C and options, in the engine section you'll see coolant tank.
Not cheap at $500 but it's carved out of billet aluminum so it's the best quality and the stainless tanks (next best thing) run about the same $$.
Sorry, not paying attention. You need a Pass. side outlet, they may make it that way as well. I have to call Joe tomorrow, so I'll ask.
