    You have a
    4g64, 2.4L inline 4, 8 valve EFI
    R4AC1 4 speed auto(also known as a Chrysler A500?) with a 3.909 gears in the axle.
    R82 being Red 82, "baja red" I think. The last two I don't know about

    Thanks..I noticed when I bought a tranny filter today the screen said A500..
    3.90 gear? Wow..I thought that was only in the 4x4 trucks.
    I guess the truck is an SE.
    Maybe the last bit it trim?
    I have factory tax and clock..

    Almost all 2wd were 3.909. 4x4 were 4.22 I believe and long bed/ext cab/auto has 3.545.

    I think the last ones(one of them) is your interior color
