Six months IS excessive. For anything. Luckily, I received my kit in a short timefreme but that was before he moved to TN, years ago.
I have been looking at @BergmanAutoCraft p/s pump w/o the reservoir and manual brakes but may want to do Hydroboost in the future. Borgeson box, Dr.Diff Viper kit and Cobra rear kit, aluminum 90's Ram m/c. Does the p/s pump need to have a different spec if it is running the Borgeson box and Hydroboost. IIRC the hydroboost doesn't require much pressure.
