looking for my old 71 340 demon

back in 86 i bought a white 71 340 demon. (my first muscle car) at the time i painted it plum crazy added a twin scooped hood and a wing. and sold it 2 years later. I recently found my build sheet! so i have the vin.# now. the car was last seen around stamford connecticut, about 10 years ago maybe alittle bit more. but since my 70 challenger is done, i would like to get my old car back. vin. # is LM29H1B278708 :glasses7:
