A '50 1/2 ton Chevy pickup My friends just got has a Truckstell Overdrive. It is in the closed drive line about 12" behind the trans. It is cable operated and the case looks like it could hold a planetary set. Any one know how these work? How do you shift them and when? How strong is it? Are there parts anywhere? Literature? Thanks, Tom
