I realize it has been a bit over a year since there have been any updates to this post but I was curious if anyone has ever come up with a replacement for the Girling 74660152 MC? I contacted AP Racing and the CP4627 is no longer available, only rebuild kits.
I have some feelers out for a rebuild kit for the Girling 74660152 but just in case the MC cannot be rebuilt I would like to find a replacement. Unfortunately MCs with a .7" bore seem to be far and few between.
