Need a seat recommendation for a 54 3100

[DENALI]

I am looking for a seat for my 54 project. I would like a bench that has a fold down center armrest. Something that would be a good starting point to have custom upholstery applied to. I am hoping someone out there knows of something that would fit well in the truck that would make a good starting point to work off of. I will be deleted the behind the seat gas tank as well.

Something like this seat but i have no idea what it came out of, i do know this particular seat had sculpting done to it before being covered. however it has a center fold down like i am after.
