Hard to find items made easy by guys who have been in HVAC a lifetime. Stay out of big boxes and go to the pros. You don't need a universal part from the place up the street, you need the right part. Take the time, spend ten more cents and get what your dad would have bought and have it fixed for good. Great store. They don't necessarily sell soft skills they sell hardware for heating and cooling. A lot of register covers I couldn't even find on the internet. Restoration hardware I looked all over for was right in my neighborhood.
