Anyone know off hand if a bed cover for a 2001 Super Crew will fit on a 2008 Super Crew with the same 5.5' bed length?

 

Not sure but sort of doubt it. This site might help:

Found it while looking for a cap for mine and wanting to compare measurements. If I'm looking at the right models and the figures there are correct it looks like the difference is too big at the tailgate between the 2001 and 2008. The other measurements might be close enough but the tailgate end is over 5" different.
