SPID and bucket seats

[bcfishon]

So I'm putting together a 72 blazer and the SPID does not list bucket seats and I'm at the point of doing the interior. I have both utility and the sport buckets and am unsure which would be appropriate for the factory originals. I've only seen a handful of the blazer spid's with the bucket seat option listed and assumed that would be for.the sport buckets?. I've seen promotional literature that shows the blazer came standard with a drivers seat and the passenger and rear seat was a separate option but personally have never seen a single seat blazer.
