Need help with part number for right motor to buy off ebay

im having a few issues with the new front wiper motor i need to buy as the 1 ive removed was submerged in water for that long that it removed all part number from the sticker so i dont know exactly which is the right motor and linkasges to order...ive seen a 2003 ren megane estate wiper motor with linkages on ebay but according to ebay it wont fit my car but the car looks exact the same...then ive seen motors for sale saying for models 2002 to 2008 but ebay does not have estate in compatable models it will fit..can anybody help me out on what motor i need to order for a 2004 ren megane 2 1.9dci (90) estate plz...it deffo needs a new motor as ive tried linking the old 1 directly to the battery and theres no life in it at all..or is there another way of getting part number off it other than the sticker?i contacted the seller on ebay with the 2003 ren megane and asked if it will fit mine but they said they need my part number to check..so im stumped...thanks:(
