is there any differance in the 2??, I got 1 here off of a parts truck and was gonna throw it on , since it looks fairly new but its a 2wd, my 98 is 4wd, otherwise I will just buy a new one for the 4wd, just curious what all the diferences where..............

 

Should be the same box, but it could have a different ratio, 3.5 to 1 or 4.5 to 1 . 3.5 is better.
