I'm looking to replace the headliner in my 96 cobra. The old one is out and I purchased a replacement from TMI. The TMI product promised to come with the fabric already attached... which I thought would save a lot of time. Unfortunately, the fabric is only attached to the front of the backboard with several inches of fabric extending beyond each edge/side. I believe I will need to trim this extra fabric, wrap it around the edges, and glue it down in order to actually install the unit. Am I correct in this understanding? Any hints or tips from those that have already done this? Thanks.
