The only real differences I saw when I was looking this spring was there is no pivoting front axle on the 7660. The axle is welded in to the frame and the frame is now going to flex like the rogators. Plus the springs are replaced with accumulators on the wings of the boom. Both changes seem to work just fine on my 7660 and mine is white, not the challenger color. I'm sure there is a few more changes and maybe someone else will help you out.
