WIW: Excellent Shape Buddy Buckets

[Boogie_Man]

I have this set of buddy buckets in my '71 that I'm thinking about trading out for a black leather bench. I've seen these estimated all over the place from $400 to $1200 and don't quite know what these would bring. They are in great shape, foam is in good shape and quite comfortable, very very little rust on the frame, one tiny hole in the driver seat as seen in the pic. The only thing really wrong with them is I can't seem to get the driver seat to adjust on the rail. I'm tall though so it's never been an issue since it's in the farthest back position. Would it be a fair swap for a nice leather or vinyl bench or are my buckets worth more? Thanks for the help fella's.
