Convert to spring brake chambers rear axles 55 LJSWX

[FBGNO]

Is there a conversion set up on the market to retrofit spring brake chambers to the rear drive axles of my 55 Mack LJSWX, or do I have to fabricate my own set up?

don't know of a "conversion set up". looking to go period correct , the spring brake set up was the addition on two chambers with rods connected to through shafts  from outside frame to inside which rods connected to vehicle brake chambers, for safety and simplicity ; install a basic two chamber system such as todays units. depending on the clearance factor of chamber mounting.

Well I think you have to start with Bolt type chambers or clamp type?  Then there is the issue of clearance.  Both have to be looked at.

 The remote chambers were because there wasn't room on the heavier axles for "piggy-backs". There were piggy back conversions for the bolt together chambers, although I haven't seen one in decades.
