I am doing the floors on a 71. I have to replace both sides. The car is a bench seat car. I will probably end up using aftermarket seats of some kind. Should I get the factory style seat brackets or just fab up some? I'm sure someone has gone this route.
If you can get a set of factory buckets that would be the correct route. But all aftermarket bucket seat vendors brackets are only suitable if you are going from bench to bucket. I understand that's what you are doing but the factory style bracket will not be compatible with aftermarket buckets. The problem with the aftermarket bracket that is compatible will put your head into the headliner if you are tall. Everybody has to do some cutting and welding just to drop it a little. If you got the skill to build your own brackets that would probably be best in the long run. I'm considering the same right now.
