Hello all. I'm looking for a new front bumper for my (USA) '87 328GTS (VIN: ZFFXA20A7H0069605). In checking out the suppliers, I'm seeing some information that is confusing, at least to me. Based on the diagrams for the 328 (1985) it seemed to me that 61747400 was the correct part number; but then I saw on the Ricambi website that that was for car up to 64761; and that 61946700 (superseded by 61946710) is for car 64763 forward; however this part number appears only on the diagram for the 328 (1988). Here's the link (looking at item 20): https://www.ricambiamerica.com/car-diagrams/ferrari/v6-v8/328-group/328-1988/front-bumpers.html?mode=split Can anybody shed some light and let me know what I'm missing? Thanks.
