Tree Counter,
Your front cap is made by Global Composites in Elkhart, Indiana.

The website is a little mixed up, but their contact page is at
http://www.globalmoldingtech.com/contacts.html including email, phone number (574-522-9956), & owners:
Stephen Beck (

Depending on who owns the molds & drawings, you may or may not be able to purchase direct. It sure is worth a try though. I sent you a PM with possible part numbers.
