What are all the parts that I will need to build a doubler? This is what I know I need right now.
NP203 from a th350-Will I need the adapter?
NP205 from a 400
Going for the Raptor 700R4.
Another crossmember.

anything else?

you will need ethier the addaptor from the TH350 and a new output to shorten the stock one in the 700. or the addaptor from advanced addaptors. you have everything else right.

You will need to get the twin stick if you don’t want to have the sticks 12” apart front to back
