Here is a nice overhead shot of the sled. As modelers we tend to get a bit overzealous about a photo.
We try to copy the photo to the exact detail. such as the board size & spacing. Remember that I mentioned that the sled was built by the work shop so they used the materials that they had laying around. What they did follow was the print, as the sled must fit the gun's footprint. Steve mentioned that my drawing was a bit too long to fit his style of cargo bed.
My drawing follows the layout for the sled seen in the photos fitted to a full size floor. Steve's floor has sections of wood blocks added thus reducing the area, making the sled slightly too long.
So you need to determine the open area of the bed & adjust your sled to fit.
In this photo we see a lever located to the right rear corner of the bed. This is part of the sled loading/locking system. The lever is pulled to raise a set of rollers.
Then the lever is lowered to lock the sled into position. No idea what that round disc does it may be part of the locking setup.
Here we see the hidden details, I didn't have this photo when I first built my sled.
The poor fellows have to man handle the sled up & into the back of the truck bed. They must be very strong men.
The sled's frame rails roll on the two rollers as the sled is pushed/slid into the cargo bed.
The front rollers help to keep everything moving forward., this is why you don't need the other rollers.
Now if the cargo bed doesn't have the loading setup you may need the other rollers to move the sled forward into position.
I don't know if the work shops installed this setup or the trucks came purpose built from the factory as it looks a bit complicated to ask a busy shope to modify the truck beds..
What a job it must be to lift the sled & gun.
Hee you see the heave-ho, looks like a real nut cracker of a job. Nice detail shot of the sled frame sliding on the rollers..
The same image from earlier but showing the end result of the sled in location. You can see that the sled extends to the very rear of the bed.
This would help keep everything secure when traveling over bumpy roads.
I have to go out for a bit & will load my drawing when I return.
