My 50 is really only a 50 according to the title, it's a mix of parts from many trucks. I believe my frame is a 49. I have both the factory 2 piece rod and a single piece aftermarket stainless rod, they both seem to have the connection point in the same place ( the joint for the 2 piece and a tab on the stainless rod) Is there a place online to access the FAM? I have a copy of the service manual but it doesn't have any pictures of the parking brake beyond the pedal assembly.
