I've been in a retreat mode literally in that I had to move the truck deeper into the garage as it was just enough room to squeeze by in front. And since the missing bags of fender and door mounting bolts are found I've been cleaning them up at the bench and thats where the letters came in. I noticed on the recessed cap of the bolts, down under paint and gunk is a letter as noted for different kinds of bolts and so I wondered just how in depth the other manuals might be. I was figuring what I saw on the online version was about it. Still if there is something better I'd like to know about it anyway.

I have the fenders loose fitted with temp hex bolts but plan next to pull it apart and double check the core. I remember shims between the upper core pass side way back in the beginning, but think I just used them under the right side fender... plus I have some inner fender grommet spacer doodads so to be safe I'll start there and loosely fit things back up.
It was remarked on by several who saw it before as "really straight" so I think I'll just try and get back to that believing that its natural inclination is to cooperate.
I know I saw a measurement diagram recently that I thought showed the body and frame numbers... ring a bell?

Give me ambiguity
or give me something else
