Excellent find and stolen at that price! Looks very clean, too! How does the interior look?
If you'd rather replace the trans at some point in the future rather than open it up or rebuild it, I've got a Getrag in my '91.5 parts truck that has at most, 12 months of use on it. This is as of about 7 years ago before it was parked and sat for 4-5 years. Mileage is unknown as the previous owner didn't have any receipts or records when the transmission was replaced. I was told it got a new flywheel and clutch to go with it. I acquired the truck 2 years ago and drove it to and from the scrap yard to have the utility body removed from it. The trans. shifted very smooth and drove nicely!
Just something to think about.
