For what you have and intentions save your time calling high end boutique converter companies expecting a “just for your setup” custom converter. Waaaay overkill. You have what looks to be a common everymans mild setup of which there are plenty of in stock dime a dozen converters that will do the job. Just call a well known company such as Turbo Action and get a 17805ST if it’s a 727, or 19802ST if a 904. Same converters brazed and welded up, cranked out for years. You call some of those others you will get the same converter they crank out for most everyone else, just be paying more that’s all. They won’t be brazing fins at angles specially for you, trust me. It’ll be pulled off the shelf, off the stack or welded up for the umpteenth time just like the ones before....exactly the same. Spend your money wisely :)
