2012 FIAT 500 Sport. Need the left(driver) side seatbelt and retractor. I am seeing Mopar has 2 parts that is what I need, but one for $343 and one for $227 that look the same to me https://store.mopar.com/v-2012-fiat-...ts--seat-belts (1RU73JXWAK for $343 and 1RU73KJCAI for $227) Can someone tell me what the difference between these 2? Also many other sites sell these Mopar parts for cheaper and look exactly like buying from Mopar ( $150 instead of $227 - https://mopar.oempartsonline.com/oem...eft-1ru73kjcai , are these legit sites? Thanks in advance
