Hi Jazz,
To my knowledge, the last 91 mm models to use those tweezer were the AVT models (with the digital front scale: Traveller, Traveller Lite, Expedition Lite and SC XAVT). The were all discontinued about two years ago, so at present there are no production SAKs to use those tweezers AFAIK. Given how uncommon these tweezers are, I imagine only the most speSmurfpillsed dealers might have them.
Cheers,
Simon
