go to JC whitney. They are having a sale on APC racing style seats, They are high back, with side boysters that will fit the contrours of your body. They are regulary 179 a seat and they are on sale for 99 each,plus if you spend $100 or more you get 10% off an if you spend 200 or moe its 15% off.
To make them fit your car make sure you use the tracks from your stock seat (should be 4 bolts that hold it on)and they just bolt on to your new ones if you choose to. I have a set on the way for my 73.
They have 4 differnt colors to choose from.
