could I PLEASE get some help?!

The fork you are searching for does not exist. Cantilever mounts were long gone by the time a 160mm+ fork hit the market. You may just have to switch to a disc brake up front.

Like others have said those forks dont exist.. but I would argue as to why they would even be needed... as if it is an older hardtail you would ride much faster with a disc conversion... likewise if an older dually...

Having recently done disc conversions to some of my kids older bikes.. no one wants 26inch so disc front and even rear conversions make for a lot faster and fun ride without upsetting balance such as if you were to put a 6 inch plus travel fork on a 4 inch duall.. or a massive fork on a hardtail...

just my 2c.... as for keeping period correct if doing a build (which would maybe be the only reason you would consider keeping canti's but then why would you want a longer for that wasnt around at the time).... if you are really attached to your current ride and really want to go mega... then just mullet it, 27.5 fork /rim/ discs on the front then glue on some canti mounts just to confuse everyone with some wifi brakes..........
