I have a 1989 Full Size Blazer. I have done a 6" lift with springs on all four corners, no blocks. I have 37" tires. What gears should I install in the diffs? Also, I want to install lockers, what ones are best for these big trucks? My truck has a 5.7 L. fuel injected if that matters. I would post pics but, I can't figure out how to resize my photos, they are to big.

Perhaps this post will help with the image resizing:
