Re: License plate screws
Hi Phil,
These are the screws that hold the license plate itself in place, correct? Are there separate screws for the frame or does that basically fall off when you take the plate off?

Re: Correct Part - Brake Master Cylinder
Wow, the info on that page was very helpful actually. Now if only Eckler's price was a bit more competitive. Their master cylinder is more than double what other sources are asking.
