Worth, TX Status: offline these are the rpo codes for the different gears, look for one of these on the sticker in your glovebox. if GT4 is on there, then you already have 3.73 GU4 = 3.08 GU6 = 3.42 GT4 = 3.73 GT5 = 4.10 you should have a 7 5/8" rear differential EDIT: i changed the 3.73 to say GT4. i had originally written GT5 for both the 3.73 and the 4.10 < Message edited by otnietdehoooo -- 11/5/2007 8:03:11 PM > _____________________________ Matt - 98 4DR 4WD click me!

It's a gov-lok at less than 20MPH it's locked up if there's wheel spin... at anything over than that, it's fully open, doesn't matter how much spinning you do... At least that's the way I read it on the eaton site... _____________________________ (in reply to 972DRBLAZER) Post #: 6
