2 kits for sale, following Overkill's thread on bulletproofing the MT410 rear gearbox. Includes all parts listed less Loctite and the part for doing this to an ET48.3. I spent $42 to do a single mod but ended up with enough parts to do 2 gearboxes. Finally just decided to go a different route. All parts new and never installed. $25 ea. CONTUS shipping included.
