I found my 14b ff and corp 10 bolt 8 lug for $300. How much (if any) play should there be before the wheels turn when you turn the drive shaft? Also, will the stock auto lock hubs from my 1/2 ton 10 bolt fit on the 3/4 8 lug 10 bolt? I know you guys hate auto hubs but they work great for my mixed snow/dry conditions in the long canyon at my house. Thanks.
