Just pick up a sled with rail extions on a 121 skid. Extions masure 12.5 in so is it a 136 or 141? What I have found is 141 but not sure. They are wps rail extions. Any one use them?
Found this on a site that sells WPS Now I have to make sure it has 8 tooth drivers the adj is backed all the way off and is tight as hell.
