Thanks sled_dog to telling me about www.rocky-road.com I got my front lock right for $319 to the door. Part number 2620. Wheeled forever with an open diff/gov bomb in the rear 14 bolt, now I'm 1 ton with a detroit in the rear. Made one trip with that and I said screw it, I want a front locker! Should be a good install along with the Spicer life series U joints I've got for the front axle that I bought from Jesse @ High Angle.
