The system has been in the market since probably 30 years and the 1st ones I saw with that was shimano 600 back like in 82. The funny thing if this makes the OP feel better... you are not the 1st one that does this and you wont be the last one for sure. Anyhow...why people don't think before doing...??? jezz...!!! You did the hardest part, to take the little cups out

Thanks. I read what I can find on the internet and watched youtube video before working on the crank. My ignorance on different types of bolts/nuts/extractors for square taper BB was my own fault. Previously I had only worked with the external BB.
