Thanks for the input. I worked my way through the online manuals you provided the link to above and couldn't find anything that gave a definitive answer. I could see Chevy doing either back in the day: leave the panel body alone and mount it to the new frame; or modify the sheetmetal to match the new frame.

Someone knows...:) Thanks!
