I recently finished upholstering the trunk on my 1930 Ford Roadster (Brookville). I am thinking about using a gas strut to raise the trunk lid. However, I don't know what length to use.

A friend told me to select any size, then measure where the location would be with it fully opened and fully closed. Can anyone give me a starting point as far as the length and where I can buy one?

The trunk lid doesn't weigh that much, but I wanted to replace the standard arm that is currently holding it.

Thanks in advance!
