It's just a 2-wheel drive, the PO told me it was an OD green Bell Telephone work truck and every now and then I find clues that he was right.
Changed out the IL-6 3OTT for a 350/350 combination.
4:11 was too steep so I put in a 3:08 (3:07?) rear end.
I really had no idea these trucks were so popular, I found this one for sale in my friends driveway when I was looking for a quadrunner hauler and that saved me from searching around used car lots ect.
That's the paint job I bought it with 26 years ago but yours looks real good!
