How do you replace the headlights on a 1966 Pontiac catalina convertible?

Answer 1

1. Remove the front bezel (the chrome piece that covers the headlights.) I believe 4 screws hold it in place.
   
   1. Invest in a set of steel hooks from Sears (approx $10). It made my life far easier than I can describe compared to the pliers.
      
2. At about the 8 o'clock position (for driver's side lights) and 4 o'clock (pass side) you'll find a steel spring that hooks onto the lens cover. Long needle-nosed pliers will remove it, but it's very difficult. It takes some muscle.
3. Feel around the edge of the lens frame and you'll find a few slotted screws. Use a MAGNETIC screwdriver to remove them. The screws are small and will get lost in the body very easily.
4. The headlight may fall forward when the screws are removed. Be prepared to catch it.
5. Remove the wiring harness from the back. Be sure to pull on the harness boot and not the wires.
   
6. Reverse the process to install.

There are some phillips-head screws you'll find with a spring surrounding them. Don't mess with them if possible. They are used to align the lights.

Invest in a CD-ROM shop manual. I found one on Ebay for about $20 and it's a digital version of the repair manual used by GM mechanics in 1966. You can disassemble the entire car down to the last nut and bolt with the guide. Best $20 I ever spent.
