Spoolmatic 30A vs. Spoolmatic Pro - parts compatibility

[cruizer]

All the 30A's are virtually identical even 25 years ago. However the Pro has a different nozzle / tube assembly that is somewhat different

I have a newer style 30A gun (maybe 6-7 yrs old), looking for tube options (45 degree, flex, etc) - according to Cyberweld's site, everything they show is for the Pro and XR series ONLY - anybody know which parts are NOT interchangeable between the two guns? So far it appears tips and nozzles are. Thanks in advance... Steve
