Maverick rear end swap

Years ago, I bought a 68 Dart GT, basically for parts. It was a 318 904 car. It had been sitting along time tires were flat with tall grass growing around it. I could just barely see under he rear of the car, not seeing the 7 1/4 I was expecting, but what looked to be a 8 3/4. It had full wheelcovers on it. Got it loaded on the trailer rather quickly, got home and unloaded it only to find out it had a Ford 8 in under it. Jokes on me.. I look back, the car was in really good shape, just missing the front sheet metal, but long gone.
