I've shared a couple of images of this truck in the Abandoned Squarebody Pictures there but here's one I bought off my Landlord for around 750$ in November last year.
A 1973, C-20 with a 350 and 4 Speed Manual Transmission. This one had been in possession by my Landlord since at least 2008 or so but it had been off the road since 2006. It was an Ex-Tree Service truck but the owner at the time died in 2006 and most of his equipment ended up at my Landlord's dump which included this truck.
From what I've dug up, this was once a Missouri truck as it was sold at Jim Robertson Chevrolet in Kirksville Missouri and according to the VIN tag it was assembled in Janesville Wisconsin.
The first time I've seen this truck was around 2009 off in the distance at my Landlord's dump but the first time I've seen it up close was around 2012. Fast forward to 2019, I wanted to try my head at doing a revival and after looking at numerous trucks I settled on this one, and here's how it looked when I seen it for the first time since 2012.
Not a pretty truck but it was something that I could build off of.
