I just purchased some new old stock Bendix brake pads on ebay as they came with OE brake wear indicator end caps.....just an impulse buy simply because they had the wear caps included.
However, I have recently purchased some break wear sensor wires for an older Meredes which have a similar ends that slots into the brake pad hole. The Mercedes sensor wire is made to connect with a bullet connector about 6" from the caliper and so I simply made a wire with a female bullet terminal to suit.
Not the same but will do the job if you get stuck and want the wear sensors to work.

P.S. Also in the interests of authenticity, I have since replaced the interim Mercedes wires with the original Lancia wires utilising the new caps I got with the Bendix pads
