They both are 4x4. The Bravada has rear discs. This car looks like it rolled in off the showroom.

When I jacked up my rear, there was a whole lot of slop, and noise going on. What would it cost to rebuild my rear. I'm not sure that it needs it even, I just thought it would be good to have the rear discs off the Bravada. I can get it for $175,,or $200 if I have the cut it out. What all would I need to do the conversion. Thanks.

 

If you do not have rear disk brakes, then you may have some fun getting the parking brakes to work. You will also need a 4 wheel disk brake proportioning valve and/or master cylinder to get everything working properly...

 

Also, check for gear ratios. A lot of Bravadas have 3.73`s, but not all of them. You will obviously want to match the gears you have in your Blazer.
