Installing bed wood kit on a 71 long/fleet

[gonline71]

I have already dry fit the bed and marked the outside hole locations. My question is this, where do I drill the holes for the long carriage bolts that mount to the frame? I have scoured Horkey's, Mar-K, Brother's LMC....and have found conflicting info. Before I make an assumption and mess this up....is there standard location or can I just put them wherever the cross sill attaches to the frame? What about the last cross sill at the tail gate....are those two I should be using? It has been so long since I removed the original bed, I cannot remember what went through those nearest the tail gate.

Thanks in advance

I just finished up mine, so maybe I can help a bit. You need to completely assemble the bed and mark the holes from the bottom using the cross sill holes as patterns. Yes you will need to use the two at the very back, skip a cross sill and drill a hole at the next cross sill, this one is inline with the back of the wheel tub. At the front of the bed you mark from underneath the first cross sill, skip one and mark the 3rd sill (which by the way has wider holes. If you go to mar-k's site they have a pretty good installation instruction sheet that will help a lot.

We provide installation information on the website that is useful for a wide range of readers and that to our knowledge is accurate. We appreciate it when it is pointed out that we missed the mark. Could you help us by letting us know just where we should be more clear in the online instructions?

Chipflyer, that is a good explanation of the process. It is a lot of extra work but if you can do this with the bed sitting on the frame and squared up it helps. The cross sills usually have extra holes and that way you know for sure which holes to use for reference. The rear sill under the tailgate has a slotted hole so you need to either make measurements on your frame for the location or set the bed on the frame to make sure to drill the wood hole in just the right place to match both the rear sill brackets and the frame holes.

The online mounting hole instruction http://www.mar-k.com/mtgholes_3-8_ofst.pdf is intentionally generic which can be used for most trucks to locate the mounting holes and it shows how to make the recess for the offset washers. When you buy from Mar-K you get more detailed instructions with dimensions and photos for your specific truck.

Thanks Chipflyer....just wanted to make sure I was correct before marking and drilling.
