Re: rear end ratio
I'm at work and just dug around in the parts computer. The deepest gear set I can find being used in these housings is a 3.70:1 ratio out of a '95 ONLY SL320. The earlier SL320s used a different carrier and the SL500s used less gear.
The housings were originally from the '86 - '95 E-class and a second one taken from the '96 - '02 E-class.
We're kinda stuck when it comes to MB parts. No joy here.
