Note these Jeeps did not come from the factory with a T-90 and V6 combo.
For 3-speeds, they had either the T-86 or T-14.
You can look for a tag under one of the top cover bolts, or the transmission type cast into the side of the transmission.
These transmissions have cast-in marks T-90, T-86 or T-14, though the T-14 can alternately be marked as 1302.
A 225 with the T-90 is near certain a four-cylinder Jeep converted to the V6.
This was done a lot, and just as good as the factory V6 if done well.
If you have doubts, post a picture looking down at the gears.
You also might look at the casting numbers on your engine.
I recall we have a casting numbers document in the Tech section.
Now for the bad news.
Donnie (Keys5a) is right.
1412 11786 is the VIN for a '62-65 2-door Wagoneer (1412) with the 230 OHC engine (10000 through 49999).
Look here:
https://www.ifsja.org/tech/figures/vin62-64.html
Most likely scenario is someone used the VIN plate and title from the Wagoneer to register a Jeep without a title.
May have been naively practical at the time, but not legal in any state AFAIK.
Question is how to deal with this.
