does anyoen no where to get a set of gears for a 85 4wd and wut type do they take the 10 bolt 7.25 or wut thx

 

All I know from your post is that you have an '85 4WD blazer.
I would suggest that you ask the partsman at your local dealership to tell you what you have. You'll have to give him the RPO code that should be in your glove box or the VIN#
If you are planning on changing the gear ratio you will neen to do both the front and rear differentials the same.

 

If your 85 Blazer came from the factory with P235 tires it already has 410's front & back ..
