To Go Wing or not?

Thinking of putting the Go Wing on my 71 Dodge Demon. Didn't come from the factory with one. If I go ahead with it, is there somewhere I can get info on measurements for exactly where it goes & the modifications I have to do inside the trunk.
I just installed a gull wing from 1st Place auto this past weekend. The measurements come with the instructions. Took a couple hours but easy to do.

Check your trunk lid inside and see if is notched out for the brackets needed. If not notched out, 1st Place has the templates to trim the lid.

It's a personal thing, but I like it on my 71 Duster.
