hello, I´am from germany and got an 280ZX 2+2 targa from 08/1981. it has 147Hp and is the pre facelift model also called series I (with chrome bumpers)

are ther differences at the L28E rings 75-80 and 81-83 ?? thint one ring has different thickness??

nissan gave me partnumber for my car (12033-P8370). this should fit. but in auctions at ebay this partnumber is fpr 280ZX until 1980. but i have one from 1981. so its possible to have other rings?

i am also not sure if the american years are same than german? nissan said 05/1980-08/1981 have partnumber 12033-P8370. can i believe nissan germany who gave me the partnumber knowing my VIN or must i open my engine to be sure?
