I used them, but I was able to walk in with my cover for comparison. They sent incorrect Chevy scrolling for my 69 GMC seat. The match was 100% dead in in color etc. they fixed it, but took a couple weeks.
If you are having your covers made, order enough vinyl material to have the bead/edge made without a break. I did not do this and I have a break in the edge/bead that goes right under the back of your knees. Not sure what to call this. Your upholsterer will make the bead/edge by sewing the vinyl over a round plastic piece. You can measure the edge bead from back to front and over to the passenger side. This is how many yards you need to have this one continuos piece. If a break in the edge is not an issue, you can save by ordering one less yard.
