Slightly off topic, this is a 64 Buick service car, conversion by Flxible Co. looks like it started as a wagon but is a 4dr sedan. Cheaper to start with a sedan than wagon.
One thing I added was small metal plate to the roof crossmember. On the 64 the dome light is only held in with the headliner. It now has a firmer attaching point. Do not know if others are this way.
He marked out where they go on the material, took that to a local place that does embroidery, and he put it all together. It was my idea to do it this way.
