I didn't realize that this was a bolt in. The width is too wide, but if the truck isn't lowered a bunch it may work with narrow, neg offset wheels.
I couldn't get to the first link, but the second one was interesting. On the bolt in suspensions instructions there was something I have never seen in any article on the subject, incuding the one on Camaro clips on the same site. That would be getting the angle of the upper control arm shafts off the doner! That is a huge mistake forgetting that! But it doesn't go into much detail. For instance that angle should be gotten when the doner is at ride height, not with the engine pulled, it does you no good then. It should be with the engine and front sheet metal installed. Then that angle should be duplicated on your truck, with the truck at ride height, front and rear. Your truck will then align just like the '82 C10 you pulled it from.
