I put my new MC and booster in my 67. The kit comes with some extra parts and no instructions. In the picture you can see some rods. When would you use those?
It is going to depend on your master cylinder. Show us an actual picture of the back of your master cylinder and the front of the booster. You want it so it isn't so long the master is pressed when it is bolted up and also not so short so that there is a lot of travel before the master is engaged.
Adam, Just to let you know they make a tool for this. IF I remember correctly it is approx.$10.00. You can now make the adjustment EXACT!!! Especially with the adjustable pushrods. Tom T.
