Brake Proportioning Valve
78, auto. My proportioning valve is leaking, when I go to the various vendors, the valve some vendors show has a hole in the section where the long rear brake line attaches to. Some vendors say this is for a 78-82, one vendor is saying this is for 74-82. Click the linnk to see a picture. http://www.corvetteamerica.com/cf/part.cfm?partno=28981 
My valve on the car does not have this hole. If I go with one without the hole, I would have to go for a 74-77. Or is this something GM change later and is the correct part now?
Thanks for you help and advice. Bill
