Yes, it will fit, in fact the 07 3500 C&C I purchased was suppose to have that system when Dodge eliminated it without notice, from the package I ordered it with. So I had to scramble to find the fold flat system because I was going to use it for tool storage, in the overall plan of my service truck. I had two choices, 1) Buy new system from the parts department at $1200. 00, yes I was quoted $1200. 00. 2) Try to find it on e-bay cheaper. I then moved my fold flat system from my 04. 5 2500 to the 07 C&C until I could find the system for the 04. 5 2500. I found the fold flat system on e-bay for $200. 00 with shipping included, 30 days later. I don't think you will have a problem.
