Center seat option?

[Big D]

I'm getting pretty excited . I am going to pickup a 68 GMC I bought in a few hours after a 4 year spell without an old truck.

Anyway, it has a couple Escalade buckets installed with a Blazer center console. Its done nice but I am going to need a center seat to haul both kids around with me. I seem to remember some late model GM trucks had a center seat that would fit in place of the console but I cant find a pic. Something that folds down like the old buddy buckets had would be nice.

Is there a vendor that sells a seat like this as well?
