Cohort Pic(k) Of The Day: One Truck, Many Chevrolets (And GMCs?)

Here’s a peculiar find by canadiancatgreen at the Cohort. Just exactly, how many Chevys -and GMCs- have been used to create this truck in particular? Anybody out there cares to guess?

I suppose that’s a positive side of the recycling business, not only do you make a living, but can keep your vehicle always in running condition. And I can see a few more spares on that bed; for sale, for further mods, or for a side project?
