Anyone ever tried a Lock Right diff in a D 60?

Thanks for the input guys, apreciate it. This motor isnt a trick hi strung piece. Mildly built 360. Idles smooth at 600 rpm in gear.The only hard throttle usage it sees is in mud and deep snow, With an occasionall stop sign burn out, or a quick burst down the highway. Mostly a gravel road truck. Was looking for an inexpensive option to a true posi unit since il be replacing those clunking spider gears. Getting tired of hearing them for about 10 yrs now. Figured if im ewplacing them, i could throw a few bucks extra in there and get the lock right if its somewhat well mannered and doesnt break every 1000 miles
