I purchased a four speed with a Rockwell T221 N3 transfer-case attached, I would like to know if anyone knows where I could find some specs on this? (What tranny it is bolted to, t-case gears, does N3 = 3 speed, is this a good case or should I look for a np 205) It is out of a '68 C10 if that helps. I am putting this in my FJ40 landcruiser and would like to know how it holds up. I have a np205 mated to a th-350 in my Blazer and am happy with the 205. Should I look for one for the cruiser as well? Thanks for any help. T.J.
