Chart compartment 67-68 chevy pickUp

[674wd]

I am hoping for some direction from someone on this website. I am restoring a 67 chevy 4WD and have a pair of 67-68 buckets and the full length bracket-mount that the seats and a chart compartment/armrest were mounted on. I am looking for any information where I can find one of these. It is referenced in the 67-72 factory assembly manual and I believe it was available in 67 and 68 before the plastic console. It looks to be a metal box structure with a small seat-armrest on top of it. Classic industries actually sells the seat cover set that includes new covers for the two buckets and this armrest/compartment. Can anyone give me a hand finding one to restore and recover? Thanks
