83 Bench Seat?

[70GMCer]

I'm almost to the point that I want to recover the bench seat in my 83 & need to know what type of seat cover to get.

The option code on the SPID says XDD1 Blue Custom Vinyl Bench

Does this code tell whether it is vinyl with cloth inserts or just all vinyl?

I also see on here & other suppliers are showing different vinyl patterns to choose from. Did GM have those different patterns too choose from for 1983?

My seat has been recovered by the PO, so I don't have anything to go on.

Any suggestions?
