looking for my moms first car

My name is Brian I am from upstate Ny.
I am looking for a 74 challenger 318 that my grandfather bought for my mother new out of high school.I have the vin,original window sticker and a old pic when it was new and thats about it,any help or advice would be great!!
I was young when I saw it last,from what I can remember it was a 318 car,my dad did change the egnine I think. It was first white with a black vinyl top,then it was white with a flake green paint,then the last I knew it was hemi orange with solid black side stripes,the hood was not a shaker but had the two vents one in each side,it was in upstate ny last I knew,again I was maybe age 10 or so last time I saw it,I am 34 now.
