    How do I determine, without yanking the cover off, what my Axle ratio is? I do not have the tag on my rear any more. I have a 1987 full Size Blazer 4x4 with a 350 and a R700 tranny.

    Thanks

    there should be a sticker in your glove box with the RPO codes for your truck. i have the list of codes on computer at home. but the codes will tell you what ratio you have.
