recently bought a 73 delta 88 royale, and she needs some help in the interior. need the plastic steering wheel column cover, door panels, and interior light bezels. have been searching online to no avail....help!

 

Are you talking about the piece of trim that attaches to the bottom of the dash & wraps around the bottom of the column ?.
(above the white "X" in the pic below)

If so I should have an NOS one in black along with an NOS vent insert as well.

 

no, not that piece....see attached for image of the missing piece(s)

Looks like the base of the steering wheel is the cracked part with the column needing some paint ?.

 

Ahhhh...so the column is just needing paint? i had thought it might have a plastic cover. thats good news i guess, can just pain the column.

 

Looks like the column is out of a '71-'74 full-size Buick. There is a small rubber ring/collar that fills the gap between the column and the instrument panel that's missing. I doubt you'd want to remove the column from the car to install one though.

If it were my car I would find an Oldsmobile column with the ring & correct shift, tilt, & turn signal stalks.

 

you might want to remove it to paint it anyway , so you might want to find the rubber piece too, or find the original olds collum.
