Where can you buy 1964 Valiant Signet interior???

I am wanting to buy 64 Valiant signet factory v8 but the interior is cashed out, was searching the web today and everyone shows 65 and up for Valiant and nothing for 64, they list 64 and down barracuda but are they the same or different as far as door panels and seats are concerned? Thanks and Merry Christmas in advance!
