I have a 05 G35x automatic, the rear differential going bad, my differential have 6 flange bolts a guy have a
05 g35 manual that's wreck will his differential with 4 flange bolts, will it bolt right up with no modification if not what will i need to do.
Thank U

 

Pretty sure it won't work because of the different final drive gearing, your X had 3.3 and the 6MT's all had 3.5 I think.
