Technical 53-56 F-100 info needed

I'm looking for information about the rear most angle iron trim part that protects and finishes the wood floor ends at the Tailgate and is a Stock trim part. It doesn't seem to be reproduced, and I don't have a stock one to look at. I've had to replace the stock rear factory crossmember that the wood flooring sits on that the trim in question bolts to. I believe the stock piece only had 4 carriage bolts holding it in place. The damaged original crossmember has multiple holes drilled in that location. See photo.

I believe the 4 correct mount holes are the ones in front of the Green Tape. There are 3 other holes in that line that I believe are not needed in Stock profile. I have folded a new edge trim part out of SS and don't want to drill extra or wrong holes in it. Who can post up a photo and some measurements of a Factory Correct trim part and help out this Old Guy to move on?

 

Brrrr.
Hope these help.

 

Brrrr, is right. That's above and beyond the call but true to the HAMB. I thank you! So the way I read that is that only 4 carriage bolts is correct. First on the ends are 3/4" in from the edge then 15-3/8" and on to 33-3/4". T

 

That also matches the 4 holes I felt were correct in the damaged piece.
Thanks a ton.

 

Dont know about 53-56 but the place im getting ready to order my bedwood kit from has them for 48-52 they might be able to help Hindsight Bedwood Vanscoy Saskatchewan

 

You’re welcome. Glad it helps.

 

I would help but my crusty 1955 comes with the optional see through bed floor.

 

F-1 beds can get really interesting.
1948-late 1950 used a sheet metal bed floor on top of the wood. The ‘48-50 bed has the sculpted bedsides and the fenders are notched. The vertical bed posts are also rounded. It’s more Art-Deco than the late 1950-1978ish bed.
How the wood goes in the early and late F1beds is a little different too. There are slight differences.

 

lmc truck doesnt have it?

 

They have these at The Truck Shop in Orange, Ca.......
