Duster Rear Window Louvers

i really like the idea of having 5 slats down the back window and 5 corrosponding vertical slats for the quarter windows. not only would it look factory but you wouldnt have to fabricate so many of them. the RRs just used double sided tape to attatch them to the side windows from the factory. the odd thing is that i cannot find any evidence of any rear window louvers to go with the side windows on any 77 and up RRs R/Ts or SCs. it has my curiosity going. i wish i had a couple of the original 77 RR side louvers to cut up and play with, because the windows are similar to the duster in lot of ways.
