I finally got my gas spring mounting brackets yesterday and I'm getting ready to install them onto my Brookville 1930 Model A.

The problem is I can't figure out the bolt size of the pre drilled/tapped holes in the trunk lid. There are 2 mounting locations to choose from. It appears to be a coarse thread. 10-32 & 10-24's are too small and 1/4-20 is too big. Is it possible that our good American Brookville Roadster uses metric threads? I've emailed Brookville 3 times and no one has responded.

If anyone out there has a Brookville and knows the bolt size, your help would be greatly appreciated!

Thanks in advance.
