188mm.... I had 3.46 in my open diff and have 3.46 in my 60% locked diff. What gear you use/need depends on the engine and trans you have. If I went to a 3.73 I wouldn't need first gear... With a 3.64 it would have been debatable if I would have used first gear.
Yes, since you have it all apart best to be safe and replace everything.
The
oil you want to use is
Amsoil 75w-140 severe gear
oil. 3
