i see. i was stating that i had the two factory spot welded long supports that came with my car in the seat. i also made the wrong assumption that the triangular pieces were attached to another long support and that it was one piece. from the pics i see that there is one support and one triangular piece. what does that triangular piece attach to? isn't number 108 in the top sedan picture the same as number 20 in the bottom picture?

but, i guess none of that would matter if i didn't mind that they weren't adjustable. i could put rear headrests in if i had only the pair of headrests, the eyelet mouldings, and the set of brackets that attach the headrests to the factory long supports in the back of the seat...? for clarity, i'm talking about having only the things shown in this ebay auction:

(i'm not bidding/buying this fyi, waaaayyy too expensive).

would that work? basically everything but the triangular pieces equals rear headrests that don't adjust. i was under the impression i would need an extra long support for the back of the seat, like in this auction:

4 total rear supports in that lower picture. but that doesn't even exist in your picture. thanks for the help!
