Thanks for the info on re-assembly.
As for the centerpiece, it did come in chrome too, just not sure for how long before they began with the painted or if you had to order it as an option. This is the only part that we've found not to be available, well, this and the handle for the glove box. Luckily, we got both with the truck.
We've gotten most of our parts either at the car show or at Mac's Antique Auto Parts.
