Thanks for the help. Sorry it took so long to reply, my ISP was having some problems last week.

What type of frame would you recommend I look for to perform a swap. A good friend of mine said we could place the body on a frame from a 73-87 truck fairly easily, but I'm having a hard time believing that. If it can be done, where will be some areas of difficulty. Or do you think I should look for a 60-66 4x4 frame and running gear? I'm assuming that I could use a frame from any of those 6 years for a swap.
One last thing, what are some areas where this truck would be prone to rusting. It has a good bit of rust damage right in front of the doors, but everywhere else appears in good shape.
Thanks again.
