I thought they were standard across all the callipers. I think they are M10 x 1.0, but give me 2 minutes, I will go and measure the stainless ones I have in the shed.
Im sure they are the same across the range. I have fitted this size stainless to Puma callipers, and a 1992 110 (not mine). I am guessing, but I think they will fit your TD5 too.
