I could use some help looking for a transmission, its a 5 speed ZF tranny for a 4wd, gas engine. These are found in F-250 through 450s. I could use even a rebuildable core, its going to go into my 75' Bronco. If anyone knows of a wrecked, rolled, rusted, or blown engine F-250-450 4wd, I would appreciate it. It seems that Lesters gears here in Tulsa has a Monopoly on the cores around town. Any help would be appreciated.......
