Uhhh... you have 3.07 gears. Then I'll assume this is an auto trans? If that's the case then you would have the G92 performance option. I thought that was just 3.07 instead of 2.59 gears. But still using the Dana 36 rear end?? After all it was only a $50 upgrade... 6-speed came with 3.45 and the Dana 44.
So assuming you have an auto with 3.07 then you have a Dana 36 and yes you can put 3.54 ot 3.73 gears in it. And, no, don't do it in your driveway unless you've done this before. As Vettelt193 noted. You could easily do more harm than good. Pay a pro to do it and do it right the first time.
