When checking the shaft parts of the adapter it seems like there is no differens between the .370 and .355 size. When using the gauge the .355 fits on the .370 gauge. Just wonder the stamps shows .355 but it seems like absolutely same size as .370. I had to use shims when fitting .355 shaft in the .355 adapter
I never received the product. I never even got a notification to say it had shipped…
Très bien et pratique pour les fitting
Great products for club fitters
