Hi Pat.
As nobody seems to have been able to answer your question yet, I thought I would have a wild stab in the dark for you...
I know absolutely
zero about such adaptions, but trying to relate it to other things; is there some kind of conversion plate required to suit your specific model of adaptor?
Just throwing it out there...

Good luck.
