where would you get a lower rad hose adapter?

[sw20>>s14]

i just got the greddy breather tank and need to install it for a track day next week...it comes with every single thing you need except for the 34mm lower rad hose adapter pipe...can anyone fill me in on where i might get one? could i go to a hardware store and get one with the proper fitting? or can i just DIY something like that? just curious as to where these are available and if any of you have suggestions...thanks ;)

i know that greddy actually sells one, and im pretty sure spl carries it, i'd just go ahead and buy it, rather than try a DIY on it, but thats just me
