Attached picture is when we converted to Spring brakes.  Left side is new dual chamber spring brakes,  right side has the single chamber "service only" chamber.    Conversion requires a quick release valve (QRV) and a park brake valve (& knob on dash), plus plumbing work. We used plastic pipe (synflex).

Next,  the way the forum is setup,  you only get so many bytes of upload for free.   I spend the $75 to get unlimited upload.   Makes showing/helping others easier.  It also helps if you are asking for help and want to show a picture.

There is different ways you could post pictures. I have to send the photos to my email and then split the screen and slide them over otherwise they won’t take sometime. Sometimes early in the morning I could post one and that’s it. It won’t let me do anymore, but T Mack  is right you could pay the museum or Barry the website master and you will be allowed to post a lot more. Good luck.
