I have a Lancia Montecarlo (Scorpion in US) 1977 and require a Steering Wheel Boss to fit an original Momo steering wheel..The hub has 21 splines and outside diameter is 17.5 mm.....can you help? I hear your Springalex unit (SB051) may be a good fit?
The SB051 is 20 spline (with 1 blank spline) but 18 mm diameter. so may be right. But this wheel fits a traditional wheel with a 6 hole fitment on a 102 mm (4") PCD. Momo wheels are normally 70 mm PCD.
