Well, there isn't any dash air vents on a 95 wrangler. There are defroster vents and heater vents, but no dash vents. Unless you are talking about A/C vents then they are a separate product all together.
You can try a company called www.vintageair.com
. They have some parts for the YJ A/C units, I know you can get compressors and other parts, not sure about the air vents though.
