The proportioning valve is summitís own brand (or no brand). The MC and booster we got last year. I canít recall the name right now bit it is a popular brand. I will post when I remember.

OK 67SS, I've sent an email to Wildwood, I'm waiting them answer.
I will post them answer, if that can help.

I red lot of forums about bore size, most of people install 1" or less. It appears that Corvette uses 1" for manual brakes. Some people said that 15/16 or 7/8 can be a good option for a better pedal brake sensation (softer).

Bore size of the master cylinder has to match the bore size of the wheel cylinders and the stroke of the brake pedal (as well as the foot pressure required since Granny Goodwhich has to be able to drive to church). A Corvette was designed not for dentist living their second childhood (that is what a Harley is for), but to road race. It doesn't behave the way a passenger car does, and Granny Goodwich really would hate to drive one. Your leg would feel like it fell off after twelve hours at Sebring or at Watkins Glen.
