OK after changing the digger rear end from an A model to a1948 which is wider and bigger axle tubes the pinion shaft was only an inch away from the transmission ujoint. OK both have the same spline and the torque tube will be only about 5 inches long compared to the original that was a total of 8 inches. Is any one else running the u joint on the pinion? I thought it out and not having to use a driveshaft that has to be cut and resplined this should be stronger and alignment is no problem--Any one got any thoughts on this type of install?
It won't be a problem, but how are you going to make up the inch ? Move the motor and trans back 2" ?
You get two come-alongs, one on each side of the car. Secure one end around the water pump, the other around each axle tube and start cranking. Voila!!!
that's the same way my Lasalle/banjo are hooked up. Originally I was going to use a Dana 44, and had modified the ujoint to work, but then I changed to the banjo, and am using the ujoint as factory. FWIW I have heard that Lincolns (some? all?) used a needle bearing version of the same joint. Mine is Ford. My coupler is made from the back part of the torque tube welded directly to the inner ball/swivel thing that bolts over the ujoint. I've eliminated the front ball/swivel from the torque tube and the factory two peice coupler altogether, for the weight. My Lasalle uses a 46-48 ford rear bearing retainer/mount. Also FWIW I slid the trans back and the pinion forward to make the torque tube/coupler as short as possible.
64 Dodge already answered it--Yes it was no problem to take 4 bolts out and slide the motor trans back the necessary amount.

The way you did the torque tube is exactly how mine will be and I will double check the rear bearing in the transmission where its visible near the shaft. That would be my only concern. Thanks to all who repliedE]
I suggest you have the trans checked out by one who knows how to set them up for racing. The trick is to tighten up the lash, and they will live.
I have part #'s for sealed bearings front and back, what little will get past the shaft/bearing/case won't hurt anything. Didn't even think about yours having stock bearings-- sorry!
I would only need one rer bearing with seals. The front is fine like it is.Only concern is the rear so if you have the # for this 39 box please send it with58@aol.com
Rand-Mine is new and fresh off the table and is very tight so I dont think it will be much of a problem . I have never run a motor like the one getting built so thats another gray area. I have 2 spare transmissions and 2 rear ***ys and should be in good shape for the time being. Working on it every day and now waiting on parts.
the Lasalle rear bearing is considerably larger than the Ford. Part of the conversion is cutting the bearing grooves out on the Ford rear mount to fit the Lasalle bearing. The retaining snap ring on the Lasalle bearing also has to be notched to clear the smaller Ford bolt pattern on the rear mount. I had read in a Lasalle tech thread that there was a sealed front bearing available, but nobody could come up with a part #, so I called the guys at my local bearing house, they came up with the numbers by dimension. I haven't bought them yet, but I have the part#'s for when I'm ready. Hopefully that'll be SOON!
