The '09 bed floor was too long to fit the '66 bed so I trimmed 3 1/4" off the front to make it fit. It dropped right in place after slightly trimming the 90* flanges at the front to clear the crossmember. I also stuck the fenderwells back in place to see how they fit against the floor. It looks really good for just the initial test fit!






Tight fit against the header panel.




The rear flange fits the recess in the rear crossmember exactly like the factory floor did. I was a little worried that the raised sides might not fit flush with the four side panels but they line up very well. The end of the raised stamping on the floor needs to be moved forward about 1/4" to close up the gap, but that's an easy fix.
