Here is what I come up with for a code 13 rearend.

13 80/82 2.75 3.75M Ford
13 85/86 4.11 3.75M Ford

Obviously you have the earlier version, so it would be a 2.75 to 1 ratio. 3.75M is a 3750lb weight rating. All it says is "Ford" for the type, Ford made the 9 inch and the 8.8 so it's no help there determining the type of rearend. But the earlier ones were usually 9 inchers, and if you look at the rear and it's smooth on the rear, then it's a 9 inch. If it has a cover with bolts, it's a 8.8.

 

Roger that. I will see the truck again Sunday and check out the rear end better.

Spoke with the owner and figured out that the column to floor shift conversion kit was a Mr Gasket #7667A. Downloaded instructions for it and there is a youtube video on adjustment. That plus the slice of the Ford factory service manual covering assembly/disassembly/rebuild of the 3.03 transmission ought to help. If it is too worn to fix up well enough, Hurst produces a kit.

 

Did the 3.03 ever come in a version with a top-mounted shifter? I’m thinking something like the top cover of a T-18 or NP435 with an integral cane shifter and no external linkage. If so, that might be a relatively easy conversion.

In the old Jeep world, the T-90 3-speed was standard from 1945 for over 20 years. Early models had a column shift with troublesome external linkage. When a top-mounted cane shifter became standard, this became a VERY popular retrofit. So popular that it’s hard to find an original column shift, which now command a premium price with collectors.

Per Wikipedia, the fount of all that is good and true, the Jeep T150 is a version of the 3.03 with a cane shifter:

Can’t say I believe that, but it might be worth investigating if the covers can indeed be swapped.

 

Update:

Victory is ours!

Bought the truck, wonky shift pattern and all. Had it most of a week. It it titled, registered, plated, and passes my state's inspection. Primary use will be my teenaged son's local daily driver. Don't trust it yet for long distances. Secondary use as my wife's bad weather beater, for which I already bought tire chains.

While it was getting inspected, my mechanic noticed the water pump making noise it ought not, so had him replace that. About 1/4 the cost to do that on one of our old FWD vehicles. Was going to have him un-belt the AC compressor as the previous owner told me it was seized. Mechanic figured it was just too large a belt and something else out of adjustment. So now it has working AC for an hour's labor and a belt. It won't freeze you out, but it does take the edge off. Did NOT expect AC in a 41YO truck.

Son has been used to Japanese I-4 sedans with manual trans and mildly worked suspensions [Koni shocks/cartridges and Eibach lowering (just 1") springs]. We figured he needed something a bit more Sanford & Son or Uncle Jesse and less Boy Rice Racer. He is pretty jazzed about it, much more so than for the sport sedans. He's been cleaning up the underbits so we can better see when leaks develop. He and my dad are plotting to clean it up and repaint it. I was just going to keep it running and make improvements over time with the help of my son. God bless 'em.

With the help of y'all, youtube, the Ford factory service manual, and downloaded instructions from Mr Gasket; we managed to get the shift pattern right and working. It was touch and go and I wondered if I was going to punt and buy the Hurst setup. But it shifts fine, now. Next steps: interior door panels and window weather stripping. In the mid-term, I have to learn how to tune such an engine for when it gets out of tune (it runs great right now, but that won't last).

Thank you all for your pointers.

Good to hear you got that shifter straighten out.
What was the fix? Flip 1 of the arm levers with the holes in it over?

BTW you are braking one of the rules on here!



WE NEED TO SEE PICTURES OF THE TRUCK!

On those shift arms, try to find a set of bushings similer to these:


Also try to find the pins similar to those shown.

The way you are now, you will wear through those spring pins, and the holes/rods will wear, making the shifting sloppy.

Glad you got it sorted out and good luck with it!

 

Yep, had to flip one of the plates. In the linked image, the plate on the left had to be re-installed so that it point up above the attachment point. Quite the fiddly process. Glad my son was able to help.

I have a couple videos that show warts and all. I need to take some photos.

(apologize for it being canted 90deg clockwise)

Will do.
