This will be difficult for me because I was not the one who dismantled it and
not going to be totally sure on how it all goes together. I will probably end up buying and old farm truck for the many pieces I am missing and to see
how some of the things go back together. Routing wires, cables, and brake lines is going to be a challenge.
Questions what kind of angle should I put on the rear end to line up the pinion angle better.? Seems pretty steep? Also not sure the lifted leaf springs are proper? Does the frames on these sit slightly higher in the back without a load. I was going for 4" lift front and back but I bought these springs over a year ago now I am questioning if I got the right ones.

Tomorrow I will try and make some kind of jig and find a good place to attach so I can lift body on and off with gantry. Then I can put doors on to check how straight everything is and brace it up. After that body will probably go on a rotisserie.
I would need to see some pictures to help you with your pinion angle question but a general google search will show you proper geometry for a regular u-joint ended driveshaft. Sometimes you need put a shim under the spring pack to correct the angle but it really should be done when sitting with the truck fully assembled. The angle can vary from un-sprung to loaded.

You have to hit the "GoAdvanced" button to post and then use the paper clip to find the files on your computer. Note they must be under the max sizes listed in the pop up box so you will likely need to resize them first. Once you have them all selected you hit the upload button and they will attach to your thread. Preview the post if you want to see it and confirm first. Hard to explain without screenshots. I hope this helps.
