I know that the 420a came out in some Dodge cars as well as my eclipse. Are they exactly the same as the one in my 1995 Eclipse? What all make, model, and years came out with the 420a? I'm trying to find a cheap wrecked donor car, but not sure where all to look.

 

they are not exactly the same.... the 420a was built by dodge for mitsu, but the neon version is different enough it wont work.

you could use other mitsu built cars for donors for a 420a (like the same year avenger, talon, etc... they were also available with a 420a).
