Thinking about building a Dump truck

[cc_bob]

My daily driver (a 4wd POS ford I got it for $200) is getting tired and it is getting to the point where I should start thinking about it's replacement. I've always wanted a dump truck and as silly as it sounds I would like to use it for my daily driver. I only live about 5 miles from work so mileage is not really an issue. I am also into working in my garden and often pass up free compost because I would have to unload it by hand.

Here's the catch, I want it to be 4 wheel drive one ton, and I want it to be a 67-72 but from what I've heard they didn't make any (except the napco ones). My drive way is about 1000' long and we get a lot of snow because of Lake Erie.

How hard would it be to change one over to 4wd? I realize I would need a transfer case, and move the cross member, get a shorter rear shaft, and a front rear end. Once all of the 2wd suspension is unbolted will the 4wd spring hangers bolt right up? Will I need a different steering box?

I was also thinking about finding a later model 1 ton chassis, or one with a bad cab, and bed and just putting a cab and front clip on it. This would be the easiest (I think) but how hard are these to come by and what should I pay for one? I already have a decent cab and small block that I can use.

Please, I welcome your opinions and knowledge.
Thanks,
Bob
