I just picked up a np 203 t case and was going to build a 4-1 doubler with a np 205 but after looking into the cost it easily while be $ 2,000 or more so im not so sure that I will do this . so for my question would the np 203 make a good choice to replace the np 200 thats in our trucks ? what would be the good points and what would be the bad ?
