I've had no problems to date with Eurocarparts. Stuart from Leeds is very helpful and if you check their website you can quite clearly see which parts are original equipment supplier, quality alternative brand or genuine part. Here is their explanation for the part numbers:-
"If you have more than one part number showing on the search results page - check the first 8 digits, if they are identical in more than 1 of the parts showing, the difference between them is their make. For example: 332456780, 332456781 and 332456785 are all water pumps for a Saab except '0' indicates 'Original Equipment Manufacture', '1' indicates 'Alternative Quality Brand' and '5' indicates 'Genuine Part'."
