look at the diff cover and you will probably see a rusty tag, with a bunch of numbers and letters on it. it will say 8.8 or 7.5 somewhere on it and have your gear ratio on it also

i always found this handy to read

ya i found the tag and all that can be read on it is that it has 4.10s the rest of the tag is unreadable. Are the diff cover different or the # of bolts used to hold them on ??
