[Roadsters] Datsun Roadster Brake Upgrade - Volvo Calipers

[Tony]

Most everything went well. I did encounter a problem (small leak) using the
manifold provided by breck1969 at yahoo.com. It appears that the caliper port
surface is not machined right. One port is slightly higher than the other,
therefore the copper washers don't seal. Has anyone encountered this problem
and how did you get around it. Any ideas greatly appreciated.
Thanks
