R&P is all that is required for an M6.

I pulled the "ham"...shipped it to DTS (DriveTrain Specialists) in Warren, MI...had them put in a 4.11 "thick" gear. DTS shipped it back...I installed. Life is good...no noise.

4.11 gear is a US Gear R&P set...cost $216.
Install kit / Replace bearings / shims / etc...cost $98.
Labor...$150.
Shipping...about $50-$60 each way.

About a week turnaround.

Rich Perkins is the man to speak with.

It is a lot of fun around town.... On the highway, I finally get to use 6th, so that is not a problem.
