70 C10 SWB Frame Measurement Needed

I figured they were oriented correctly and square to the frame rails, as they seemed to be, because they lined up perfectly.
All the slots I put in were in the front frame brackets.

Glad you mentioned that. I slotted all the holes on one side so the frame brace would line up correctly on that side without having to tweak it to fit. I only had issues on one side or the other based on which side I bolted in first. Mine is centered side to side at the trailing arm brackets and the frame is square to within 1/8 of an inch as I couldn't get it exactly perfect. I almost wish I would have just bought new frame rails from classic industries as I had to straighten a number of areas where they must have high centered the truck on a rock at some point over the last 40 years. That way I wouldn't have had to cut the frame, weld it, and deal with questioning if something wasn't square. They are just under $2K for new frame rails.

It should be OK if it will line up correctly and you can get the front end aligned to spec. I was lucky that my frame was in good shape to begin with.
Good luck with it, the brace seems to really stiffen the frame.
