I emailed Classic Alfa about the improper curvature for use on the left side. C.A. response below. (Larry is an Alfa owner I ordered parts with)
Thanks for the email and apologies if you aren’t happy with the badges.
Back in 2018 I mentioned to Larry that these badges are sold under one part number as I believe AR originally formed the curvature whilst the badges were warm. I also believe AR may have had these badges listed under two different part numbers in their parts books even though there was only one tooling for the badges. I mentioned to Larry that there is only one curvature available due to tooling issues from the manufacturer.
Our manufacturer can only supply one style of which we have tried trial tested on an original car. Whilst removing the original badges we found that the factory had used some form of mastic behind the badges to fill any gaps. When we tried the badges on both pillars, we decided that the gap behind the badges was very minor.
These are the only badges we can supply and I have informed Larry about this and he mentioned that he was also concerned about the colouring being not the right shade.
You’ll probably find there are so many thoughts and conspiracies on forums these days however we have spoken to our manufacturer who is the direct source.
If you decide you can’t use the badges then please return them back to us for a refund.
