My kits were stitched together by auto upholster, Kevin, from Creative Options. He is on the other e30 forums. All I have to do is glue them on, but it is harder than it seems. I have my profile on the member profiles if you want to take a look at what I have done. You might be able to stitch in new centers, just need to have a good sewing machine. I will try to sell my 4 black/gray cloth covers to anyone when I finish the last panel, passenger door soon for dirt cheap. THey are in good condition and the only one with wear is the driver door from where you elbow rubs when opening the door.
