I want to run the ORD Doubler with the AMC TH400. I know that I will need to get a hold of an NP203 and an NP205. What applications can I find the correct ones in? Yes, I am a newbie :barf: and am not too savvy on swaps. Any info and help is appreciated. I want to learn and ain't afraid of gittin dirty while doing so. Thanks for taking the time to read this, Keith aka Tigger4X :jeep:

Not sure about the reduction box for the NP203, as to which one you need to match your TH400 from behind an AMC, but the NP 205 should be the one from behind a Th400. This gives you the female 32sp input. You may want to consider having your own adapter made rather than using the ORD one. it works out way cheaper.

the 203 you need is one from behind a TH400. From what I understand to get the 203 to bolt up to your TH400 you need to change the output shaft to a standard GM peice. Not sure of what else will need to be changed though.
