I have a 96 V MAX 600 long track and I want to put drop brackets on it. I found a set on ebay but the guy says they will only fit the 121" track version. I am wondering whats the difference? Does the skid not bolt up the top idler to the same three bolts on the tunnel sides? Does anyone sell the drop bracket for a 90's V MAX 136"? Any help would be appreciated. you can also email me at firstname.lastname@example.org. Thanks again guys!
