85 ranger rear end to 89 Bronco 2

[yukon72]

I need to replace the rear end in my Bronco 2. I have a 85 Ranger parts truck. I have done the search and read the posts. It looks like I will have to move the spring perches to use the ranger rear end. Is this straight foward to do?

anything else I will need to change?

Bronco has 4.10 gears and Ranger has 3.73 so will swap front at same time- have to take it out change front u joints.
Bronco has 2.9l and al4d 235r7515 tires. Will I notice much with the change in gears.

I do have another Bronco 2 just have to check the gears out on it.

The Ranger rearend is a bit narrower than the BII rearend. I wouldn't use it myself. The 3.73 gears are going to hurt your performance some as well (4.10 is actually ideal for 235/75R15 tires).
