I see. Um… buy a two pack of these. You can get them off of Amazon, Target, Walmart, or Retrospekt’s website. Before having my SX70s converted to shoot either, I used these so I could shoot 600. You just stick ‘em over top of the 600 film pack, and your SX70 will work with the faster film speed. https://www.amazon.com/Filters-SX-70-Instant-Cameras-2-Pack/dp/B0C9N2QDSF
