I have a '97 Legacy Outback with 2.5L engine, manual transmission. I'm pulling the engine to change the timing belt, fix oil leaks (cam and crank seals), change clutch parts, etc. I'm having trouble identifiying the correct timing cover gaskets since there were three versions in '97. How do I find the date of manufacture (month and year) of my car/engine or some other identification number to help sort this out. Thanks,
