canon 60 t3 type shutter release wireless options

Hello,
I have a pair of Canon Eos bodies that use the 60 t3 type shutter release connector (5QD & 650). I am not having much luck finding the Canon LC3 wireless shutter release. Are there any other options? Might there be an adaptor that converts this type of connection to a more modern one so that a current wireless shutter release can be used?

Any suggestions would be greatly appreciated.

regards,
m.a.d.

Canon used to sell an adapter to use a 60T3 on the EOS3, so this is an option.

Another option is I may have one 60T3 left somewhere (my T90 is dead), so if you make me an offer (I'm in France, but shipping might not be too expensive for this), you could get mine.
