OK< My suggestion is this, look at your serial number plate, and find out exactly what yr your machine is, on the LX 865(and other models) they had a early version and a later one, and not all parts are the same, so you need to know what yr it is, from there I suggest calling Messicks, 877-260-3528 or go to there site, email them,
https://www.messicks.com/
they are a highly skilled shop with great techs and knowledgable staff willing to help you, , when needing info or parts on NH equipment
THAT< or remove old one, and look for a part number on it, there should be one
unless maybe over time someone modified things and went aftermarket and from there WHO knows, lots of china junk afermarket parts out there some like to use,
