Added R180A info.

If anyone has a R180, C200k or M226 ring and pinion set laying around and they could verify the pinion diameter and spline count that would be nice to add.

If no one get's to it between now and then, I will be installing 4.10's into my 180 & 226 in the near future. I will be able to spec out what you need.

See if you can get hold of Steve (Rugged Rocks).... He may have that info stuck in his head.
