bucket seats sit lower than a bench.
If your a tall person then it wont matter but if your vertically challenged then that will be something to consider.
I noticed it in my 68 dart which was a bench seat car and I drove it for a few months with the bench. Then when the buckets went in, I was noticeably lower and it became a lot tougher to see the leading edge of the hood without a pillow.
Probably not an issue for any average sized male but I am a female @ 4'9" so it was a problem for me. I almost went back to the bench but I paid a lot for the buckets so I am not going to give up the buckets. Might consider that if you have "another half" that might be driving the car at some point.
