Mike, thanks for the point in the right direction. However this truck has the vacuum actuated rear two speed axle and no switch or cable on the transmission shifter.
There is the remains of a cable coming off the original vacuum "switch" under the cab, so my axle remains in "High" all of the time.
Getting the rear axle to shift is also on my to do list. Any recommendations on the best way to accomplish this will be appreciated.
