Need a hand identifying...

"Off the driver side pan rail itself: 22(double stamped)801534Y 2558611"

so it reads 22801534Y 2558611. I assume these are stamped number and not cast in case? There should be a raised boss with stamped vin numbers on it might be pp or pk(the assy factory) xxxxxxx (year digit, car factory, and last 6 vin) xxxx (assy date) xxxx (number assy that day). see if you can find them easy from there.
