Hi ,some of the tonearms that have removeable headshells use the nuts and bolts that retain cart also to hold a finger lift, the Sumiko Premier MMT arm was like this, Needle Doctor had some of these at one time I believe. You could possibly fashion your own out of a 1/4 in. piece of copper strip sold at some ACE hardware stores. Look up the MMT arm on audiogon to see what these look like. Hope this helps David.
