Spring Brake Chambers

[randygk]

What is available for spring brake chamber replacements. It appears the diaphragms from Napa aren't exactly correct (& and my brother thinks we will die if we touch the chamber with the spring in it), and the complete chamber and stem from places online are NOS with who knows how old the diaphragm is. Has anyone found a replacement for whole unit or at least the pots?
Thanks

These are for front and rear service and rear spring. I installed some on my front chambers and they do fit.

As for the spring brake chamber removal, just ensure they are properly caged and you can open up the service side (smaller clamp). Just DO NOT attempt to open the spring side (large clamp where it says DANGER!)! Spring side is replaced as a complete unit.
