I purchased these to place seatbelts in the rear of my 02, but never got around to installing. I bought them from a member on the forum. They are new, just dusty from sitting for a long, long, long time.
$50 plus $10 flat rate shipping.
I have had this packed away for years, but never ended up using. This is a vintage Cibie Rear Round Fog Lamp. Excellent condition. I never mounted. Included is the original box and instructions. $120.00 plus $10.00 flat shipping.
The material will reduce the panel noise transfer and aide in noise reduction. I do not have a specific dB reduction specification. Density at 3/8” is 4.0-5.0 per lb.
By the ear test there is a good amount of reduction, or softening of the transfer of sound.
Hope this helps.
