7.5 Lockright/shop says there is none

[Resurrection Ranger]

Yeah that no slip is kinda steep I think though. Isn't there something called a Trac-lock or is that another name for the Lock-Right?

Yeah snows a commin. Just but my winter set on this afternoon

I think the Trac-Lock is like a Detroit Locker, requires gears to be set up. Not really familiar with them. You could also just look for an 8.8 locally in a yard with low mileage and the L/S and the 10" brakes. For less than $400 you could up-grade to the better rear end, bigger brakes, maybe a better gear ratio and such. Try using car-part.com, I've always had good luck with them.
