Best substitute bench seats 67-72'?

[Coley]

Anyone know which bench seats are the best substitute for the originals in the 67-72 models?
GM?....how about Dodge? any other successes using different bench seats?
What about complexity to fit and install?
I saw some in one of the threads that looked like it came out of mid 80's? How about newer than that?....or 70's? or?
If anyone can share what has worked for them, I would greatly appreciate it.
Backstory, I've been looking at a good deal on a local truck but it is need of a bench seat. There is some sort of weird bucket seat arrangement out of....who knows what?
Many thanks guys!....I'm always interested in good feedback and stories

All Good
