Well, I saw another post that made me think about this swap. I want to take the rear bench and front buckets from a new charger (or 300 if it fits) and put it in my 71 satellite 4dr. From what I've seen the rears will drop right in, no issues.

My question is on the fronts. What exactly is necssary to replace the bench with buckets? Im guessing that if I just drill holes and bolt it in, the floorpan is not strong enough to properly secure the seats and will probably end up ripping out over time. Do I need to have some sort of bracing welded to the underside, or topside of the floors to spread up the force? Both? If extra bracing is necessary can they be bolted in or is welding in the only option?

I would also like to add in three point seatbelts at the same time, but thats another discussion.

Thanks in advance
