Thanks Bluestar. I should be able to handle that on the SCT.[&:]

I remember reading that the 4.10A were better than 4.10M gears and less likely to whine. How will I know what I'm getting? Looking at American Muscle's website, it does not make the distinction. Also do I also bring the gear oil to the shop. Royal Purple synthetic?

If you go with 4.10's the last letter will be "a", 3.73's will end with the letter "n"....These are the Real FRPP Gears. As far as Oil, I used RP as well, and even though the claim friction modifier is already in it, I chose to have Friction Modifier added as well..........Zero Issues with any of my installs using this proceedure, Good Luck with yours. Also, Steeda UDP's are a good bet, to help with getting into the Powerband quicker and you'll have Gas money left from your $1000.00 Enjoy...
