Brad, The final decision is yours, but let me chim in on something. When I first met you, you reminded me so much of myself, when I was your age, it was amazing. I like you, had collected many antique trucks through the years, with ideas of restoring over half of them. I, as you may know, was working on 5 trucks at the same time. Well needless to say that approach doesn't work unless you have a boat load of money somewhere to draw from, & a lot of spare time. Here I am 25 years later, with not one finished truck to show off. Just had a bunch of incomplete projects. I came to the realization that the only way I was going to finish a truck, was I could only have "one" truck project at a time sitting around. That's why I have since whittled my collection down to one COE, & I have gotten more done to it, in the last year, than I have any other in multiple years. That being said, if I were you, I'd be trying to finish one of those Wrecker projects you have. Being in the Wrecker business, what better way to promote yourself. Now back to the question of a 600 series trucks you're speaking of, they were not that scarce, but were the least desired of the Heavy Duty GMC Line. The 700- 900 Big Cab trucks were more popular, & practical,because of the larger cab, & were also better looking. Medium Duty Customers, that wanted a Heavy Truck would order a 400, 450, or 470 series truck, so the 520, - 650 style trucks were kinda left out alot of the times.
