where to mount rear spoiler on 73 duster

You are NOT going to cut the top skin of your deck lid. All you do there is drill two holes just large enough for the pedestal mounting bolts to slip through. The cutting takes place underneath.

I know the black paint in the pictures I showed earlier makes it difficult to tell much about the hole and bracket. Aaron will be coming home tomorrow for the weekend, so I will try to get better pics.

Be patient,
Jerry
