Hello i am new to this form
i need some help, i am looking for some centercaps for my oldsmobile cutlass supreme from 1966
the wheels that are under it are from a 1984 camaro i believe , i will attach some pictures
can someone help me with the centercaps.
i just dont know withs ones will fit. I dont want a chevy logo on them haha so centercaps that are all black would be fine but one with an olds logo would be the best.
i am living in the netherlands so just ordering some is not a good option because sending them back if they dont fit is just to mutch trouwde

sorry if my english isnt the best
i hope someone can help me
Kind regards
Sanders
