I am doing a custom bed and cant figure out what year bed i have. i thought it was a 56 longbed but Mar-K cant find the bolt pattern in thier books.

please state the following regarding the bed you have on your truck-i dont care what year.
year
long/shortbed
stepside/fleetside
total strip length

then starting at the tailgate end, measure your bedstrip hole spacing +/- 1/4" from end of strip to center of bolt head/hole

note measurements like this for example;
0.5, 12, 23.5, 34, 50.5, 58.5, 61.75, 68.5 and the rest has been cut off-i shortened the bed so my total strip length is 71.25.
