Based on that I'd guess it's your original trans. It's not likely that someone hunted down a replacment with the right assembly date back when that car was on the road


Post a nice clear pic of your engine stamping as well as your body stampings if you have them (or just e-mail them to me if you prefer) I can probably offer you some further info on the trans stamping if you do.

*Also, can you post a pic of the date codes on your Rallye wheels? (dates are stamped right near the valve stem holes) Do they all have the same dates or not?
