Its got a few issues, some electrical, some body, but mostly transmission. I hope I get all the info i need. im looking forward to talking to you guys in the future.
If it aint broke, get a different project.

Keep in mind you may be way ahead of the game by finding a used transmission rather than dumping a lot of money into the one you already have.

If the truck has a 4 speed transmission in it, It will most likely be a SM420. This transmission was used from late 1947 through 1967. It is a great transmission. It is very popular with ones building rock crawlers. The PTO was an add on unit, and should have a cover on the side of the transmission where it bolts on.
Have fun.

From what I remember those are nearly impossible to break so that probably isnt the problem. most likely something went wrong with the clutch. my friend said after the clutch was replaced he started it, put it in gear,heard a big bang and now nothing. im gonna drop the trans and check that out. Is the PTO deletable without ruining the trans?
