I got all new lock cylinders for the doors and the hatch because the hatch never had one. Im stuck. Apparently theres something that goes in between the lock cylinder and the latch for the hatch. Theres a gap of about 5". Ive tried bar stock, but the lock cylinder opening is smaller than the hatch latch. Anyone know where I can get this piece or have a picture so I can do my best to replicate it. Thank you in advance
