the following might be helpful for those who tow or are going to change the size of their tires. the code definitions for the gear ratio (shown on the door tag as "axle") are as follows:
18 -- 3.08
19 -- 3.55
26 -- 3.73
27 -- 3.31
H9 -- 3.55 limited slip
B6 -- 3.73 limited slip
4.6 l models -- 8.8" diff.
5.4 l models -- 9.75" diff.
i don't know for sure if these apply to '03 and '04 models but should all years prior. also the 8th diget of the vin will indicate which plant manufactured your engine.
6 -- 4.6l windsor
w -- 4.6l romeo
L -- 5.4 windsor
if any of these are incorect please post correct info.
hope this is of some intrest, brian
