My car- 96 dodge avenger, 2.0L

So heres my dilema, 1200$ to rebuild my auto transmision, or ~400$ to swap a manual into my car. I think i know which one im going to do. I've already obtained a manual trans(nvt-350?), shifter, clutch cable, and clutch pedal for 200$. I have on order a knew flywheel, clutch, pressure plate, and throw out bearing. Now i know for a fact that im going to need a differant mount on the trans side. Which mount do i need to obtain and from where? I DONT know if i need differant axles, if i do, which ones and where. Help is much appriciate guys. Thanks in advance.

You should be able to go to your local autoparts store and purchase the mount for it. Have you obtained a Haynes manual for your car yet? You may want to do that as well.
