The parts list shows that both the 610 and 630 have the same base, although one of them shows a superceded part number. The caps are different part numbers, according to what I could find on them.
ok so how to I get a threaded base? I'm scouring the planet for one. I need a part number or a machine shop that will do it
I’d say that if you brought- to the machine shop- your OEM base (unscrewed and off the tank) and the new cap (and a pic of what the end product looks like) they should be able to fabricate one pretty easily.
I’ve been outta the loop awhile. Kids work etc…Just throwing this out there…I would be happy to run another batch if there is interest.
