Windscreen wiper adapter for old style wiper blades!!

Hi all I just recently bought a 1992 MR2 and the Wiper Blades need changing. The main problem I am having is that since it is an older model, it has the older style windscreen wipers. This means that they have the old fashioned screw on blades (I’ll attach some pictures). However I know there are some adapters for them, but they don’t work and are the wrong ones I bought one from euro car parts which seemed to be the wrong hand and do not appear to be genuine Bosch ones as stated online. I was wondering if anyone could tell me what system they are using on there MR2 and how they fit new Wiper Blades as I am having some trouble finding the right adapters so I can fit modern blades on.

There is also another issue that the passenger side windscreen wiper is curved however not even Toyota themselves seem to be making these anymore so if anyone could also tell me what they use would be super helpful.
