Before I fully weld it all in I did a couple more body adjustments to finally make sure it all measure out OK.
All cross measurements were within a 1/4 inch, most were dead on.
This is really critical as I found the frame is pretty badly bent in the rear, I had to use 2 inches of spacers at the drivers body mount behind the rear seat to bring everything level.
There was so much rust the poor old girl just kind of collapsed on itself. I'm confident I have it all straight now. My measuring tape has been my most valuable tool.
