MC lists a 4:11 ratio 8" electric locker but my door post label says I have a B03A rear end(8" 4:10 electric locker). Is a 4:10 and a 4:11 ratio considered the same ratio? I know its a newbe question but I want to be sure before I buy a new rear differential unit. I have a lot of slop in my drive train and I'm at 278,000 miles so I think it may be time to replace some drive train components.
Thank you all for your help ahead of time.
