hi this is for a used GM A/C DISTRIBUTION DUCT PLENUM w/RH LAP VENT ASSEMBLY for a 1973-77 Monte Carlo, El Camino, Malibu/Chevelle? WITH Air Conditioning this is used with a little damage as you can see in the last 3 photos so make sure you look over all photos should be a very easy fix for a hard to find piece it was pulled from a 1973 El Camino and I think it fit other model cars so make sure before buying it is sold as-is no returns so be sure it is for you I have most of the vents and duct work I will be listing as I get time so if you need more send me a massage and I will let you know if I have it look over all shipping options for the best deal...
