1. All 97+ q45 diffs are 3.69?

2. I can use j30 5x1 axles with the 97+ q45 output shafts?

3. Anyone know of a method besides shimming to lock this vlsd up so that it can function like my welded stock diff
Or a inexpensive option that will give me a ratio between 3.69 and 3.90

Thank you for your time
