Give VELVAC a call on 800.783.8871. (Central time) I just broke a support post on my mirror and even though I did a thorough search on the VELVAC web site, I couldn't come up with much info on what parts were available and how the mirror came apart. As long as you have that VELVAC part number they should be able to help you. I got the part I needed and info on how it came apart in record time and at a very reasonable price compared to the cost of an entire mirror head head (10%). Definitely worth a call.
