Old Car and Bike rambling

The desire to put rearsets on my cb750c has been kicking around in my head for many years. I've always felt my short legs didn't feel comfortable with the cruiser style ergonomics of the original foot peg placement but I didn't know how to mount rearsets.  Roughly 3 years ago, I found a set that I liked and ordered them though I still had no idea how to mount them without spending the money for the cognito moto brackets.  I'm sure I'll end up spending some money for one of their fine products but they just seem too spendy for me, so I kept that option as a fallback in case I couldn't figure a way out. The rearsets sat in my garage but nothing came to me. At some point, I even bought some old brackets for a cb750f but didn't have an appropriate bolt to make that work. My swing arm swap bolt modification kinda caused an issue with mounting the part, but I don't remember the details around it now. The easy and lazy solution was always to use the rear passe...
