What kind of seats are these? And steering wheel questions!

Hello all! I'm trying to determine what all is in my car.

Here's a picture of the seats. Are these considered buckets? At first i thought it would be a split bench but i couldn't find anything that looks like it. Maybe cadillac or electra from the 70's.

And i believe the wheel (and maybe the column) are from a 69-70 skylark. It is a tilt column if that helps. Does anybody know what year and model it's from exactly? Also would i be able to purchase and fit a 48 buick wheel onto this column?

Your guess on the seats is pretty good, they do have that GM 70s vibe.
Also pretty good on the wheel. That style was used on all the GM midsize cars (Chevelle, Tempest, etc.) in the sport packages. The only difference was the horn button as the columns were the same for them all. Don't know if the original Buick wheel was splined the same. These were popular with rodders in the 80s and 90s, but then the muscle restorers took over the demand side of things.
