I found a 9' stepside bed recently. It's a '70 model but I think I can easily change the fenders to the older syle. Here's a link to a photo of the donor truck.

I plan to keep as much of that as I can. I also bought the 4.10 posi rear axle. Now I've got to find some 19.5 single wheels.
By the way...welcome back tons o fun. I missed you.
