This is the PS / RH side 1/4 window filler panel piece from a 1958 Cadillac 2 door coupe. This will fit all 1958 & 1957 Cadillac's 2 door hardtop models, Including Eldorado Seville, but please verify that it is correct for your application before purchasing it. This is screwed on the inside of the body and has the felt window seal on it. This piece needs to be removed in order to remove the 1/4 window and can easily get lost in a restoration. This does have some surface rust on it and should be sand blasted and painted before use again, but is otherwise in good shape. Good used parts that can be hard to find. Comes as shown, Sold As Is. Please let me know if you would like any other info. Thanks
