Hey guys. I have a 4 speed that came out of a 91 dually, and as far as I know it has an NP241 T-case with it. I bought this while over here in Iraq and had a buddy pick it up for me. I am gathering parts for my return home build, and I plan to run the SM465, but trying to decide on my doubler. I have seen the 241/ NP205 doubler's, as well as the 203/205 doubler.
which is stronger?
which is a lower low/low?
any other benefits to one or the other?
What SHOULD my spline count be on the 465? and aside from drilling/ tapping the case any other mods have to be done to the 203 for mounting?
Also, I already have a 32spline 203 off of my TH400 and the t-case (241?) that came with my 4 speed.
