Hot Rods 66 C10 Build

Building a 66 C-10 w/292. Looking for a vent window delete kit. Found on online from One Piece Products but when I call their listed number I was messaged phone had been disconnected. Does anyone know if they are still in business? Or, does anyone else offer a kit for a 66 C10?

 

It's a sign. Don't get rid of your vent windows. They's traditional.

 

Can't hook you up but I built my own on my 66 Suburban.
Made brackets to hold window channel in the forward part of the door, purchased channel from supplier in long lengths.
Used a generic power window kit from Specialty Power Window, nice product.
Made a pattern out of masonite and had new glass cut.
