Wanted: 1939 Convertible Top Hold Down Brackets

I am still working on my 1939 Packard 110 Convertible, I haven’t been able to locate a set of the part of the convertible top front bow hold down brackets / clips (please see circled in red in the photos below), I was hoping that you could get this email out to members in an attempt to locate a set for me, I have the three pieces that attach to the timber bow but not the three that screw to the inside of the window frame. Any help would be much appreciated. Please email david@ccl.co.nz
