100% impossible (as a drop-in kit) due to the nature of the integrated rail of the 4.3.
The difference is that the 5.1's rail was not integrated. Out of the box, it comes without a rail, but predefined holes could be knocked out to allow installation of a rail that comes with the gun.
It is these holes that 9Ball uses to affix the wide body kit and strike/SAS kits.
