Thanks lopemaxx. That is encouraging…though there seem to be a lot of stories about differing floor pan scenarios in trucks…some having dimples and some not. I'll find out soon enough. I wanted to get in line for RogerKoop's brackets while they lasted on the parts board if the likelihood was that I needed them.

…but I'll just wait and take my lumps when the body comes off in the next month based on your experience.
