I have a GV overdrive unit that I have no use for. It came off a 4wd 89 F350. It is complete with uncut wiring. It does need a rebuild and that is just sending in the clutch pack section as a core and receiving a rebuilt one from GV. It has the adapter plate to bolt to a 1356 transfer case. No drive shaft and will only work on the 1356 t case. It will fit other applications with the proper adapter. I'm asking $400 plus shipping. A rebuilt clutch pack is $800 so buy the time you add everything up with shipping your $1400 into it vs. $3000+ from GV. Price is OBO. Its located in Southern California.
