Gears & Axles - M9 installation

So how are the M9 rear ends shipped what parts come assembled and what needs to be assembled?

The person thats going to help me mention if the axels will have to be disassembled in order to put the stock backing plates on?

If someone could clear this up?

And will i need to upgrade to the chrome moly torque arm and tranmission crossmember?

Daily driver so not going to track a lot.

And with the M9 would you guys recomend 4.11 or 3.73

Thank You

The Moser M9 is the Moser fabricated rear that comes complete with the torque arm and transmission crossmember. Check out this link. http://www.exoticperformanceplus.com/performance_parts/index.html?item=1324

Step by step instructions can be found at this link for the standard Moser 9 inch f body rear.

I'd go 4.11 if it is an N/A 6 speed car, 3.70 for an automatic or higher horsepowered stick car. Bob
