EZ-GO changed their F-R shift linkage somewhere between 2001 & 2002. some 2001 models have the newer single cable, while some 2002 models have the older double cables. The only way to be sure is to physically check your cart. The photo below shows the newer style (1 cable) on the left and the older style (2 cables) on the right:

fun engine November 15, 2016
Reviewer: Blake from Goldsboro, NC United States  
this was a great choice to replacing my Robin original engine.  I will say that you need to make sure you order the correct kit. I have a MXT and somehow it was ordered as a Workhorse.  The instructions are ok, but make sure you are willing to figure out things on your own.  My engine needed the two 1/2" lift washers to make it work.  don't use a bracket to hold the muffler as mine separated from the bracket the first time out. use wire or a spring to support it.  Other than that it is a great investment and the tech support does a great job!
