Hello and I'm Back.
I've noted down the comments, descriptions and advice and studying those to incorporate my plan thanks very much. for a good start
I just finished the purchase of the 2 trucks. The 1964 is not in as good of shape as pictured but worth the $3000.00 and will go through a complete remodel, but I will drive it until I get the 4wd and frame set up and then move the body over with a full paint and rebuild. The 4wd is a 1966 K20 292 4sp with 4:56 axles. The axle is the one with the bolt on front and rear pan. The transmission is missing the gear shift.
Now I've got to make some choices. Do I rebuild the original equipment and install higher gears. The engine, trans, transfer, Frame and axles all look in good shape. The frame has no rot and the shackles and springs are very good. Or I can install a 350 Auto mated to transfer and use newer model axles. The 350 is out of a 1977 K20 with C6P chassis and I remember that I was told it was a 4 bolt Main. It is whether I want an automatic or standard.
I studied the independent front suspension and it will be to much engineering to accomplish.
I will need to add power steering and power Brakes, Any advice would be good. And I will change the springs to give a better ride as it won't be used for a work truck. I have my K30 for that.
I have the shop and assembly manuals and been reading those and studying the rebuild projects on the trucks. Right now I'm compiling my Todo list of items to build the truck that will make a good statement for a Custom Chevrolet Truck with all the trimmings.
So Thank you for your advice and input. And I will figure out how to post pictures as the project progresses
