Looks like a great start for an '02 project. Be sure to check the pedal box, which is under the fuel, brake and clutch pedals; they are very prone to rust. Also, I'm guessing the rear shock towers are in good shape? They *can* be replaced if there's rust, but it's pretty major surgery.

I have an e21 3.91 open diff, if you want one for the 5-speed conversion.
