Nope, don't sell 'em any more...
I sold my company. But I can refer you to an outstanding mfr who sells direct: Ronco Plastics...they make TOP quality, thick-walledroto-molded tanks, and have more than 400 shappes and size--over 100 of which are non-rectangular--to choose from..and for a VERY reasonable price. I'd bet they have one that will fit your space. And you can spec your own fittings sizes and locations, to be installed by them when the tank is made. About half their catalog is on their website at:http://www.ronco-plastics.comIf you can't find what you need there, give 'em a call for a fullcatalog. They're great people to work with.
