8.8 swap

I have read through every page in here and the only question I have at this time is how do I know whether the rear end is open or posi or what? I know there is a marking on the drivers door about the rear end but I do not know what I am looking for.

The Door Sticker also states what type of rear axle is in the car.

41= Open 8.8 3.27 ratio
42= Open 8.8 4.10 ratio
43= Open 8.8 3.08 ratio
44= Open 8.8 3.73 ratio
45= Open 8.8 3.55 ratio
46= Open 8.8 3.73 ratio
D1 = Limited Slip 8.8 3.27
D2 = Limited Slip 8.8 4.10
D5 = Limited Slip 8.8 3.55
L73 = Limited Slip 8.8 3.73

The limited slip 3.73 is the most common.
