The FX-16 comes with the 4age motor and the standard 85 thru the 88 nove came with the 4ac motor. the tranny's will not inter change. Now if you had the 88 ss nova with the 4age motor than they would interchange. But those ss nova's are really, really, really rare to find. I would say they are more rare than the fx-16's are. They where only produced for the year of 88. I have only seen one in my life time and I am constently on the look out for one that is for sale. If you do not get the FX-16 fix'ed would you be willing to part it out? If so my email is
