Looked at her again today. Definitely has TWO hydrovac boosters. has anyone seen this setup? does one go to each rear wheel or one front and one back??? looks like they go to the rear? hard to see where they go. The master is a duel resivor, the cover bolts onto it not a clip on. truck is a 292-6cyl 4 speed with low 4 gears all together. does NOT have a 2 speed rear. should this truck have a 2 speed rear?? pto driven dump works like new. Does any one have a hydraulic schematic for this type of system?? I can't find much info online other than the hydrovac itself.
