This one if you can find it, as it's discontinued.

You can look through this list to see if any of the Vanguard heads shown as using the QS-52 will work. Then put it on this mount.

I wish you luck as trying to match an already owned tripod head or window mount by like shoes takes a long time and is usually frustrating.

This head might work. It shows a QS-51 but the 51 and 52 might interchange.
