The frames are pretty similar in some areas, but very different in other areas. Namely, the wheelbases may not line up. Early J-Trucks had 120, 126, 132, and 165 (very rare), before they settled on just two, being 120 and 132 for the J10/J20.
Now you can kind of get around that by using the bed from the J10, and the cab/front clip from your Gladiator. Although you wont have the round tail lights and such.
Another thing to be aware of is that in 1980, FSJ's switched to driver drop front axles. When this happened, the floor of the cab changed to make room for the transfercase. You can get around this, but its something to be aware of.
The rear cab mounts will also be different, as a '63 will use the old spring style mounts, and the J10 will use solid rubber mounts.
There are lots of other differences, but not any that would effect you. That come to mind anyway. Obviously suspension mounts, engine mounts, the frame horns, cross memebers, etc are all different.
I will use all the drive train from the 81 motor Tran and Transfer case
I-am going to try and use the steering Column out of the 81 and all the wiring
If I use a 2 or 3 inch body lift will that help.I know I will have to move body mounts
Any ideas would be useful?

What do you mean by driver drop front axle
63-79 FSJ's had the front axle pumpkin on the passenger side. 80-91 had it on the driver side. This is why the floor changed in '80, because the transfer-case now was going the other direction.
Ok yes I knew this
Is the cab bigger on the 81
I measured from the back of cab to end of front fender both are 100 inches. Just fills bigger
Yes this 81 is a long box so I have to figure out what to do with the box
This is from the '74-80 Jeep parts catalog, which may be available on CD-ROM at RockAuto, and is definitely available on paper at BJ's. Might be worthwhile for a project like this.
