87 Avanti Lore Chrysler Heater/Air distribution system - 87 or recent year Chrysler Air & A/C Controls on dash - from 80's K-car. Controls hard to service. Cable usually a problem. Pushbutton electro/vacuum air door control The heater valve is located under the hood along the heater hoses. It is not uncommon for the cable to become disconnected either at the control or at the value. You can manually move the value under the hood to adjust the temp. The 1987 Avanti uses 205X60HRX15 fronts and 215X65HRX15 rears on 7" wide rims. To stuff a wider tire on the rear would require a change of offset from factory rims.(although a "70-75"profile will probably fit,the rear only, height is not the problem ) The lower profile "60'" in the front clears the wider fender profile of the wheel opening while maintaining the "Stude Avanti Rack" that we hold so dear. Here the height is a problem for cornering and bumps to not fracture the front fenders. ------------- 87 Cruise Control = 87 Monte Carlo ( all) -------------------- The 3rd brake light on the 87 convertible was off a Jaguar. I think you could use just about any rear parcel shelf style from a Ford, GM or Mopar and then run a separate wire from the brake light switch. Brooksie (May 2009) ---------------------
