Door Threshold Repair – Identifying Walkout Door Threshold and Repair Options

basementdoorsrepair

The walkout door in my basement has a cracked threshold. I searched again and again on multiple online sites, Home Depot, and Lowes trying to find a make & model similar to mine, but couldn't find one. Does anyone recognize what this is and what are my repair options?

A quick update so the question can be closed. I ended up cutting out the old one and installing a new adjustable aluminum threshold from Home Depot. I had to saw open the hard black plastic and the aluminum ramp, breaking them into pieces. I also used an oscillating multi-tool to cut into the door jambs and scraped the old caulk around the perimeter. Finally I pried everything out. Installing was relatively easy. I just had to cut a few wood blocks to fill under the door jambs. With some cleaning, a fresh paint and caulk, the end result looks half-way decent:
