Could anyone use swivel bucket seats?

I was told they were a factory option for a 73-77 Chevelle, Monte carlo, Laguna, Olds, etc.
I know they're not truck buckets but if you're having a hard time getting in and out of your truck this might make it easier.
They need to be recovered and needs a 3/4" weld on a 6" piece. I'll post pics if anyone is interested. Shipping probably would be too expensive as they are heavy.
