Brake Booster Mounting Nut Size

Hi I recently purchased a 79 GMC 1/2 ton and the PO removed the brake booster and master cylinder and lost the Nuts to mount the brake booster to the firewall. I'm not sure on what size nuts are needed to remount the brake booster so I was wondering if anyone could shed some light on this.

It's been a while since I've had one off, but I'm thinking they are 3/8"-16
