Hey all, need diff purchase help (vin Decode)
 

as it says im in the process of trying to buy a new (second hand) diff for my car and trying to find one that fits and has the correct ratio.
what i need to know is what diff (part number ratio etc) these cars have
my local scrap yard gave me these vins to base from
c250td 2021282f836930
and a e320 1240522c281934

i have a w202 c280 but are sure one of these will have a similar diff.
i need one with abs with the highest ratio i can get my hands on

Cheers Heaps for any help people!!!!!!!
