Good day, I am looking for information on the bore size of a stock master cylinder for my 88 Iroc Vert. The car has disc in front and drums in the back. I have been through the forum and have also called a few part places and have come up with the following.
Cars with rear drums the front bore is 1.25" (31.75 mm), rear bore is .945" (24 mm).
For cars using disc on 4, the bore sizes are 1.42" (36 mm) for the front, rear bore is 1" (25.4 mm).
Can someone confirm if this information is accurate? Thank you
