Troubles in Bed?

[youngerestorer]

I just took the old wood out of my bed (1956 3200) and I assumed it would be a long bed at 89", but after doing some measurements my inner inner bed measures about 81" 3/16. I have never heard of any bed length like this, I thought there were only three bed lengths for the task force series 77", 89", 97", so this just makes no sense to me. Has anyone ever heard of this length or encountered it? Any help is greatly appreciated!

it is a 77 they measure from top of box to tailgate the wood is going to be longer

I ordered a set from Mar K assuming it was a long bed and the boards measure exactly 89" so wouldn't that mean the boards would be longer than 89"?... Things on these trucks can never be easy
