lots of guys have put the 16 wide into the s chassis. but its tight. not sure about the zx but would probably be the same. not sure what chassis you have as you saig 99 and thats the year they changed. snow checked models are he s chassis and later models are the zx
just make sure pitch is the same or you may need new drivers as well.
What is the lug height on the 144 compared to the stock height? The 16" wide is no problem with a little work but I don't know if you will have enough clearance for a 2" lug even with 8 tooth drivers on a mxz. I had to rivet from the inside out in a few places and put on XP drop brackets to avoid any rubbing with the 16".
