65 Fury seat differences

I have a 65 Fury 3, 2 door hard top. The seats aren't original , I have no idea what the are out of. The rear seat sticks up a couple inches above the package tray and looks crappy. I have noticed Sport Furys have a funky rear seat back that dips down, and the package tray cascades down behind it to provide a bucket seat effect.
What other seats fit a 65 Fury? I'm guessing a B body seat more that a C body seat. I'm hoping someone knows offhand.

A pic would help

I would think pretty much any 65 to 68 C Body 2dr HT rear seat would fit with 65-66 being the best choice.Usually Plymouth C's use a shorter lower cushion on account of the shorter wheelbase.65 and 66 Sport Furys and Dodge Monacos use the cool bucket seat style rear seat with the raised package tray.The 65 package tray is made out of a formed press board type of material which warps really easily...the 66 raised package tray is plastic if I remember correctly.Neither one is being repopped...only the standard type parcel shelf which was used in the lower line P's and D's.And if you want to get picky 65 Sport Furys had two types of seat covers...one with a stiched seam the other with a heat sealed seam depending on production date.

Thanks a ton Furyman. It looks like my seats are out of a larger C, I was searching old threads and there may be a diff between hardtops and sedans also. That may be where my problem lies. I was hoping someone could give me a reference point, my seat back sticks up 2 1/2 inches higher than the package tray. I did not know if this was correct or not though.

Pretty sure sedans are different. I have a 65 Fury I sedan and have parted out several hardtops.

I wonder if the luggage rack would fit on my trunk.
