Not familar with that early air brakes. Are the bolts in the same place if so I don't see an issue . some of the first trailers I pulled did not have spring brakes seems like the mounting bolts were the same though. next question do they have a reserve as well as normal service air system? Are they S cam brakes or wedge brakes? If the mounting holes are the same any truck parts dealer would have the boosters/chambers/cans look at this been around trucks all my life and don't know the proper term. I've heard them refered to as chambers and as boosters but this is the first for cans but that may be correct.
