Yes to question 2.

All years to 89 are supposedly the same. The 964's fit, but the spoiler is electric and intergrated. The hinges on the 964 are also spaced farther out.

Best bet? Buy a used one and do the body work yourself. Take off your fuel door and take it along with the lid to be painted and cleared. You'll need the fuel lid so they can try to paint match it.

Good luck. I'm taking the slow road to fitting a 964 now but may look into a duck later on down the line.
