now that is weird.
I had understood that the adapter was used for cars with lower gear sets;
My car (not bought stock) has the correct plastic gear for the (standard) 3.55:1 gearing;
I found an adapter that would be perfect for retaining the original speedo gear, and the adapter would correct for my desired 3.90:1 gearing.
I would have presumed that "standard" gear set cars would not have needed any adapter.
