Go buy a set for a 98 12V 5 speed... Same as the "upgraded" sets you can buy at half the price, minus the fancy braided stainless hose instead of the standard rubber.
advance auto parts has a cast iron hydros with bleeder screw at the slave i had south bend and it failed with in a year i ran advance for less than half the price and i am happy with the product
what year are the cast ones for? i have a set of sb hydros for the g56 tranny is the storke any different from the rest. i know the rods are different length but i wonder if i could just replace the rods on the g56 with older style rods and run that?
