All I think that it is unlikley that a Volvo O/D unit would fit , unless their supplier is 'Gear Vendors'... Gear Vendors makse a unit for our 727 transmissions, it replaces the tail shaft and doesn't affect the trans mount or drive shaft length. I got one to use on my Imperial, then decided to keep the Imperial all stock, so I used it on my Hot Rod that has a 727. The point of all this is that if you really want and need a O/D unit on your Imperial, go to Gear Vendors and get one that will handle the torque, and will bolt up with no modifications. An added side is that the unit will give your Imperial six speeds forward... all automatic. George ...'with the soon to be beautiful '55 &'56 Limos's... "Rev.
