yes, ask at the office, many yards do pull drivelines, and because they were optional there won't be any way to know what model/year to look for .... an OD will have a handle/knob under the dash that, if original, will have "overdrive" on it .... if you can find one from 68 or after it will have a syncro first .... and of course the other choice would be the 3.38 rear gears, not likely found in a yard but available new from Patricks
