Folding Seat Hinge Covers

I have been on a great streak lately of buying parts from the great members here and then finding the parts I already had.

I just purchased some hinge covers(right side) and naturally came across the ones off of one of my cars. I believe the ones on the left to be for sure 68 model covers but I have seen other listings and some discussion that the ones on the right are 68? Whichever ones I use will get painted black but just curious which ones are correct for my 68?
