Need help identifying

[mblackburnjr]

Hey all.I am trying to find some info on this truck.On the title it says Defense Property Disposal Office,Crane Naval Weapons Support Center....This was purhased in 78 from them.
It is a 67 swb stepside with some weird options. Radio delete,Ac,firebox,(which is now gone),fire extinguisher,and everything has its own lable.It also has small back window and is automatic 6 cyl.I am trying to figure out gear ratio currently.Its also painted a really dark grey.Not silver like on the tag...Does anyone know if the navy bought trucks and converted them,or if the general added this stuff. I cant find anyone else who has anything like this.
