Swappin 02 03 subframe onto 04 05 F4i

My buddy just got an 04 F4i and doesnt really like the long seat. Would he be able to swap the subframe from an 02 03 model onto his 04?

yes it can be swapped but u need alot of things: subframe, undertail/under tray, tail light, rear cowl, seats. i ithink u might need the wire harness and lock assembly....not sure tho
