I just feel so stupid that I didn't even think of it before. I jacked up the rear end and took off the lugs, went to go grab my 6 lug 16's off the 89' and was actually stunned to find out it was 5 lug. Then I remembered the paper work that showed new drive shaft and u joints. And the fact that the E-brake does not work. Plus it makes sense, the amount of weight I removed is just amazing to me. So to handle the weight he probably swapped to something more robust.
