I have the old Remco driveshaft disconnect on my 52 GMC pickup. It does allow towing, but the disconnect is not exactly the most convenient. I have trouble to get it to re-engage, since the sliding collar is keyed to keep the u-joints in phase. Most times I just jack it up to slide under (low hot rod truck) and line it up with my hands. Never had good success with the knob to engage. Disengage is easy, it works fine with the knob. The disconnect does work, it just is not the most convenient.
