Hey guys, new to the forums. I did search and find nothing.

Im wondering if anyone knows the part number for a full engine rebuild gasket kit for a MY99-MY00 version 6 sti ej207 type ra motor, im finding about 4 different part numbers online and all of them are saying the kit is for either 98-98 or 98-02, then on a different website it says the same part number is for 02-03, then on a different site its saying 02-05 and its doing my f&#$% head in, all the prices range from $400 to $1100 for the same part number so if anyone knows the part number please let me know before i lose my absolute sh#t

Part numbers im finding: 10105AA380, 10105AA351, 10105AA3519X, 10105AA350


Cheers
