Perhaps you can take a super high res photo and send it to them to date.
But seeing as I can make out the writing but its almost gone I would say it lands in the 60-90k range... but I am far from an expert.
This was the reason I ended up staying USDM, well that and my prodrive kit sets me almost equal footing with the v8.
And I was able to get a full drivetrain for the same price.
