The rubber boot on the controls for my Long/Landtrac 360DTC FEL ripped. Finding the specific part for Landtracs is tough. Anyone know a place I can order a new generic boot by dimension, for example? The base of mine is say, 3"x5" and 7" tall. I've scrolled through hundreds of Amazon listings looking for a match with no luck, and my local tractor place says they need a part number. Anyone now where I can source a generic boot?
