Sorry to have taken so long to reply, but I have been away racing.
As to why & how I modify the spindles is a result of a few years experience building race chassis not just modifying Alfa`s for racing as I have done since 1969. FYI, I am totally comfortable with my knowledge of suspension design.
The need to share how I determine the steering arm position and the design of my fixture is something I don`t need to do, along with the pre-welding process, alloys used and heat treating process. Of the
many spindles I`ve modified since the first 101`s & 105`s in 1969, I`ve not had a failure or complaint with it`s function.
I share quite a lot with this forum, and the Alfaracing list, and most find it useful. Some things you are just not going to have shared . Sorry......
