Thanks for the welcome red58!

here are pics with the sills in the approximate places where they should live,
Linky of the sills
as you can see none of them line up, I was wrong about the second one back it doesn't line up either. Everything I'm seeing says the 60-62 frames are different than the 63-66, bed wood and sill part numbers are different between the two. It would be helpful if some one would be kind enough to give me dimensions on the frame mounting holes on a 60-62 frame and maybe pics. I hope I can just buy the '63 sills and all will be good, is it possible I might have to replace the front mounts that are riveted to the frame? Thanks, joe
