Again, thanks! | | | | Joined: Jan 2006 Posts: 49 Shop Shark | | Shop Shark Joined: Jan 2006 Posts: 49 | 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.

lemme see if I can find it .... you're makin a "custom" bed, so it can't much matter what it started out as .... you must know whether it's a stepside or fleetside .... if you made it a "custom" length then long or short don't matter .... so the list of measurements must be what you're askin about .... so you're trying to figure out which new strips to get for your "custom" application?
wouldn't the hole position be determined by the frame you're putting it on, and the number/position of the cross sills? and Mar-K didn't tell you Chevy beds don't have 8 cross sills?
more info on what the bed is for might help

Bill okay. thanks. um-this bed used to be a 56 longbed chevy. however Mar-K says my bolt hole spacing longways doesnt match anything in thier books. im hoping one of you can help me prove them wrong. OR barring that-one of you has a truck with spacing i can make work cause im replacing angles and strips-i can make my spacing anything. its going on a 1981 jeep wagoneer frame. bolt spacing matters not. its going to be a dump bed-8 cross sills for reinforcement. so im still after your bed strip bolt pattern so i can see if its somthing i can make work for my app. if spacing comes close to even and especially if i can cut one or both ends to make work then i will pretend its that year when i order all strips. thanks! | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | they won't be wrong cuz Chevy beds have 4 cross sills, plus the front and back, regardless of length and year, so only 6 holes in the length [actually fleets have 2 holes close together at the front, so 7 there] - why not just get unpunched skids the right length and make holes where you need them to suit your cross sills? .... although the xtra cross sills on a 6' bed sure seems like overkill
Bill | | | | | Joined: Jan 2006 Posts: 49 Shop Shark | | Shop Shark Joined: Jan 2006 Posts: 49 | but they should be right as i am measuring angle strips(other strips were gone) and i know those holes are valid as some of them are for bed and fender mounting/braces i dont want to punch my own as i have to buy special ribbed bolts. also im somthing of a non-commital purist in that i prefer that parts i mod/use to be able to be referenced to some off-the-shelf part. when i complete vehicles i make a 'build sheet' and laminate it and put in glove box listing make/model/year/part number for every part i install. that way my wife or i can pull into napa and give part number/application and get the correct part instead of guessing. also saves on special orders if needed on road trip or out of town.. mark SO-please submit your bed strip bolt pattern. thanks! PS-my bed needs a lot of cross sills-its going to be a dump bed for firewood and landscaping projects. see here; http://yepthisismylife.blogspot.com/

the 55.2 - 66 step beds are the same, but the cross sill placement varies between the series because the frames differ, you might have a bed some one got from a 60's truck and put on their 56, adding extra holes in the process - I put a bed from a 63-66 on a 58 frame and had to redrill some mounting holes in the frame cuz cross sill position was different
"bolts with only washers" could refer to the bolts that hold the bed on the frame, which have the large square hole washers and don't go thru the skids, but do line up with the cross sills
at any rate, a fabricated framework [instead of "extra" cross-sills] will be required to make the bed strong enough to be a dumper, so make it to suit the hole spacing in standard 56 shortbed skids [6'], no extra bolt holes required in them, the extra holes for added cross braces will be mount holes thru the wood, you just need extra square-hole washers for that
