for those doing later 4 speed swaps- the short one that is- your late pig front drive shaft should work, especially if it's stock and you're lifted or shackle reversed. at stock height and shackle position, you may be almost an inch long in front. The early 60 series drive shaft has the same bolt pattern as the late pig and is a perfect fit without mods. the stock pig rear shaft may work if you're not lifted much, but the flange is about 1" closer to the front of the truck with this trans and tcase, so if you're lifted, and have an extra 1" of wheelbase like I do, the stock pig shaft is too short to not worry about. the shifter position for the later short 4 speed is about 4" OC back and about 2" OC to the left/drivers side of rig from the stock opening of the floor shift 3 speed equipt FJ55 trans tunnel cover that is found on 73 vintage and similar drivetrain rigs. If you swap the t case shifter HANDLE for the PIG tcase shifter handle(not the crank arm, but the handle part), you may not need to do any cutting or mods to the boot. The stock 60 series tcase shifter handle will require cutting the rear of the tcase shifter opening and patching the opened up front, this is why I used the PIG shifter handle on the 60 series crank arm of the tcase shifter assembly. either early or late floor shifted tcase PIGS boots and the pigs handle will work even with the 2LO mod done to the bracket of the shifter. the trans shifter will require patching. if you use a 4" hole saw, you should be able to weld the cut out into the recess needing the patch, then notch the patch with the hole saw to retain the uninterrupted circular cut out. I used a thicker piece to make the patch- I used a 3 3/4" hole saw- a 3 7/8 might be just about right, but for a tiny bit of extra meat at the weld, a 4" saw should be about perfect. I was able to tap the thicker material in the patch for one shifter boot screw, then used threadserts for the other three. I used 1/4" cause that's what I had

I think there are some SAE bolts on the bumpers too

, but even the bed had metric threads cut for fasteners

It'll give me something to fix if it ever finishes

the gearboxen have plenty of room with the factory motor mounts. the long 4 speed or a 5 speed would require a new trans tunnel cover and moving the rear support bow for it back about 3". maybe only 2...
