Does anyone know what size the fittings are on a master cyclinder for a 67 Camaro with factory disc brakes? How do you determine master cyclinder line fitting size - do you go by O.D or I.D.? I am going to order an after market booster and master cyclinder and need to know what port size to order. Seems like most options are 3/8, 1/2, or 9/16.

Any help is appreciate
Thanks

Pipe is measured in ID and tubing is OD, so brake lines would be measured by OD. Jegs or Summit sell brake line. I am not sure how to determine the size for your brake system though.
