I have dumb questions
 

Ok, so im new to the world of mechanics so forgive me if what i ask is dumb. i have a 07 freestar with a failing transmission the engine is the 4.2 v6 essex and friends and i would like to do a manual transmission swap on it for shiggles but theres nothing on the internet for it at all. aside from it not being worth it and being a stupid idea yada yada i need to know 3 things-
1. is it possible?
2. what manual transmission can i use for this if any?
3. what modifications are needed to mate them?
if anyone has any info it would be greatly appreciated thanks!
