Bed mounting Hole locations?

[chev3600]

I'm putting a 54 bed on a 49 frame and dont have a lot of decent parts to go by. After much online searching, I'd guess someone probably has the measurements I need sitting right in their garage. I'm trying to find out the locations of the four (or 6?) main mounting bolts for the bed. I'm not sure what the size of the hole is either. Maybe someone has a wood kit around and could grab a pic? Not sure if I'll need the 49 or 54 locations.
I've searched a lot of forums and came up with tons of other info info. Mar-k and gmcpauls are great.
Thanks!

I didn't think that a '54 bed would plop right onto a later frame, that there had to be some mods to the frame.

Yeah, no plopping. I had to raise the bed floor due to the kick up of the frame. I bought the chassis bare and the bed sides alone also, So I dont really have any reference points.

I'm kinda in the same position with my build, my '53 had an International bed on it when I bought it, and I'll replace it with a Chevy bed and have to trial fit it a few times I'm sure.
