68 Dart GTS history?

I bought a Y-2 yellow ‘68 Dart GT in Phoenix when I went to school there in 1987. Previous owner told me the driveline was transplanted out of a 340 car. 340, 727, 8 3/4 w/ 3.91 SG. Might have came out of your car…
Sold it before I left. :(
That's a huge possibility! I have a feeling though that the original engine was blown up, which is why it became a parts car. I have a plate that came on the car (original or not, no idea) that had a sticker from 84 on it as the last registration date. Can't read it real well but it's RSE-993. The other picture is what the car looked like when we got it in the late 90s. Thanks for all the replies!
