Can you do an autostick conversion on an 01 dodge neon SE and if so what car is best to yank the parts from?

You could.

You need the usual 4-speed-automatic-Transmission, the Autostickshifter AND the Autostick-Cluster. Without that cluster it won´t work (at least on a NGC - >2003).

Were to get that things ?

Good question - these parts are absolutely rare. Look at Germany or UK for them.

Also see 2gn.org for more details :-)
