Checked the specs on the vendor's website. The maximum height for the door 17-23/32" and the door travel height is 16-47/64". So, your 18" is out of the specs and definitely will not allow for full access. The Wind lift system should work it is not an exact replacement and it does not allow full access but it is best that I know of.
