'70 Dart 392 Project; what direction?

The big hump closest to the rocker panel is where bench seats mount. Push the bracket inward and you will be good. Note the dimples in the floor close to the hump? That's where the holes go for bucket seats.
Ah okay that makes perfect sense now. I was assuming they would utilize the same outside holes with me needing to drill through for two new inside holes not using all 4 new holes. Thanks!
