[Roadsters] roadster and Z car front caliper mounting bolts the same size?

[chalsted at comcast.net]

as some of us have both Z cars and roadsters, can anyone tell me if the caliper mounting bolts on a Z are the same size as those on a roadster? bought a one owner 260, haven't picked it up yet as last time I went to get it the front calipers were locked up and I didn't have the tools with me that I needed to pull them 

thanks :-)
