Like the others said, yes, it will be about 1.5 inches shorter is all.
Many have gotten a cage from a F-150 and put it on their Trac and it fits with no problem...
Unless,,,, you have a hard cover. If your Trac has the OEM cover, the cage is too long to swing open, you have to unhook the center hinges and life the cover a bit to swing the cage.
I would have traded, but my wife gave it to this lady she works with. Her son got a Sport Trac last week and did not have one. I told him about this site, hopefully he will join.
