8.25 Centre and Sure Grip issues

Pana, I'm having the exact same problem. I have decided that the SG unit is wrong. Its possible there was a difference in the carrier sizes, but it has nothing to do with 2.45s. Every unit I've seen offered for the dak was 2.56 and up. I've never heard of a dakota with 2.45 gears in it. The shortest I've heard of in a dak was MAYBE 3.23. NObody here seems to be able to offer any ideas as to why it won't work or what's going on. I'm going to try to find a different SG unit for my rearend.
