It's so easy to butcher the small screws that hold on the top of the master cylinder reservoir. The cross head fits a Japanese standard screwdriver bit so, unless you have the proper thing you have to be very very careful with your Phillips screwdriver or, like me, you'll need a replacement. I had to resort to drilling mine out having exhausted other remedies. There is an option to change out the screws to Philips head in Stainless steel but those don't look right to me. This part is the real deal and although it's not pennies to buy is the genuine article and they don't charge a fortune to post it out to you quickly.
