Hello guys, I'm gathering all the info I can before I start the conversion from non overdrive car to an R-11 in my 47 Clipper Deluxe. I have made a few phone calls to Packard experts and got some good info but am waiting to hear back from another two. My main concern is if the R-11 input shaft is the same as my non overdrive input shaft. I know I need my driveshaft shortened or get an overdrive driveshaft. I have the solenoid and governor and will handle the wiring and relays. Do I need a different trans cross member? The weather is getting warm and I need a project. Thanks very much in advance. Richie.

You shouldn't need a new main crossmember at the trans but you will need the bracket to mount the OD lockout cable and will probably have to drill new holes for it on the driver side. The crossmember you may need is more of a plate that bolts to frame right before the X. It holds the snubber bar and the coil spring like rubber core insulator assy that goes under rear of OD, Not sure if your existing snubber rod assy and bracket will work with the the OD-- maybe the plate will but I think the OD rod version is different and maybe longer. You will need to find the insulator assy and possibly some shims or a spacer plate that goes between the OD and end of the insulator.

On the snubber there were apparently two types in 47. The original which was more like the prewar versions with something like tie rod ends -- rubber molded into a round ball like affair at each end of the rod and then this style which is what they switched to for 22nd on. A straight rod with replaceable rubber donut like bushings on each end
