need help!

Gotta question, im not seeming to find alot of part for my 65 dart 270, the interior it what im mainly looking at only cosmetic but still necessary ya know like seats and stuff haha , ok so I need either new seats or to get them stripped and redone, i should mention this is a rolling resto. im also looking at chaning the crpet and i need to put a new headliner in as its gone. there is also a crack in the dash pad that has been poorly put back together, i did however find locks and keys to them in the junkyard from a dart so ill see if they will work sometime soon since i cant lock the thing yet. so my question is were can i find some parts on the cheap and yes ive been to the yards i got a few more to go tho, and what cars and years will crosover and be compatible to mine. like i said i have 65 dodge dart 270 its auto on the tree and 4 door bench seats. any info is greatly appreciated as this is our first restore together the hubby and me and We have never done a dart. Thanks
