I didn't find them online either.  Doesn't mean they aren't there, sometimes I miss things. 

I would guess that Fairbanks/Schaben/Riggins R Co or similar would be better outlets for the running gear but I do not know that Cactus doesn't handle them.  I've talked to them about large (12000 and up gallon) tanks, don't really know how much smaller stuff they do myself.
