Arch, a FLAP is and argument or heated disruption. Wikipedia lists, BROUGHAHA(SP).
udidwht, sometimes the only sure way is to take the part in and have the clerk make a visual. Take your VIN in with you, come times there is a code that helps. Look for part numbers and manufacturer's name on the parts. Not to sophisticated, but these things help.
I've even had clerks tell me there isn't anyone that makes a oil filter for a Chevy 454 and showed me in the book, sometimes they can't think beyond their experience, it's also called a 7.4 liter.
Good luck.
