Keep in mind the car stuff isn't always better than the truck stuff. I recently got my Hydratech hydroboost and had to decide on master cylinders. I figured I'd go with a late model Vette but the bore size was smaller than the truck master cylinders (relationship to weight of vehicle and bore size, or fluid displacement). Most all the GM cars were a inch or under. Late model trucks had some 1 1/8". I found out that a '99 truck master cylinder (4 wheel disc) has a 1 1/4" bore size.
