The T19 for the Scout does not have the same front end. The Scout has a longer input shaft and I do not know the size of the bearing retainer on the Scout version. I also do not know the bolt pattern on the Scout verses the Ford version of the T19. Look at this page for further information http://www.novak-adapt.com/knowledge/t18_t19.htm Novak has a lot of information on their site.

Mating the Dana 18 to the T19 requires that a new output shaft for the T19. I assume it is shorter and has a different spline count than the original one. Novak also has these.

I know that the Dana 18 is an offset transfer case. The Scout axle is centered. The original axle in the Willys is slightly off center if I remember correctly. However if you look at the pictures and diagrams of the Willys wagon drive train and frame it shows that the rear drive line is not parallel to the axis of the truck. It shows that the rear axle is more centered than the transfer case output. So they came that way form the factory. I have looked at drive line design documents and they show that you can off set the rear axle and transfer case output as long as they are parallel to the each other and the axis of the truck. The Willys did have some vibration that might have been from this issue but it was only at higher speeds and under hard acceleration from the Chev V8 in it. Also the engines and now the 4BT is offset about 1 1/2" from center which will correct some of the transfer case output offset.

I am not going to do a spring over on the Willys. First I do not like how high that makes them. It looks bad. Also it makes the Willys to high in terms of rolling over and stability when a SO is done.

I believe that my Scout axles are 3.54s. The rear might have been swapped to a 3.73. I was thinking 3.07 gears with the OD and 31 or 33 tires. I was not aware of the 2.73 ratio. The Willys axles are 4.10 which will not do. The Willys rear axle is a Dana 44 but has 2 piece axles and small brake drums. I figured it would be cheaper and better to swap in a Scout 44 rear axle as all I would need to do is weld on new spring mounts then do a ratio change. I was not planning on doing any spring changes in the rear as they are new springs and are already 2" wide. Also not much of the added weight of the 4BT would be on the rear so I figured that the current springs will be fine.

What road speeds did you see with the 2.73 gears? What size tires were on the Scout with 2.73 gears?
