Bed mounts

[caminokid]

I noticed something when I was putting the bed on the frame I am using. The mounts above the axle are taller then the ones on the 3/4 frame. The bed has a wood floor. The bed that was taken off has metal floor. why is the mounts different? You would think that the mounts would be the same as the other. I cut the heads of the rivets off of those mounts so I can replace them when I am ready.

Here is the frame I am using. The mounts here are mounted to the sides of the frame.


These mounts are at the left edge of the pic. they are in a totally different spot.



Now that I look at it...there is two center mounts on my frame...and none on ther 3/4 frame.
