Tim,
Sounds like quite a project, the 9' beds are great on these old trucks and get a lot of stares as you drive by. Mine has been in our family since new but spending all it's life in Minnesota the winters have been a bit rough on it. The hardest parts to find will be the 9' sides, everything else is available new. The cross sills are more heavy duty than what was used on the 1/2 and 3/4 ton models and there are 4 of them in addition to the one directly under the tail gate. Every thing bolts together, no welding required. Nice bed wood kits are available and the metal wear strips can be purchased with the holes already punched. These beds are heavy once assembled, you will need a few people to help with the lifting. I mounted the cross sills to the frame and attached one side at a time (with help) but went relatively well. The running boards and aprons will also be a challenge to find if you don't have them. Don't give up on it though, a truck like that is great to have when your done.
Good luck on your project, and keep everyone informed on how you are coming along.
Tom
