Trying to keep everything correct and build time correct. Car has standard tranny, drum on back and disc on front.Does anyone know which MC came on the car? Part # or any description? Any available? Even the right core will work. Thanks in advance.

Power or manual brakes? That is what will make the difference.

 

disc on front and drum on rear

 

you already said that in your original question.....he's asking if you have POWER brakes or MANUAL brakes.

Brake booster?....or no brake booster?

 

No booster.

 

ST code master cylinder. No power brakes on a manual transmission W-30 in 1972.

 

Manual brakes use the 2 bale wire master cylinder. ACDelco part number 18M1079.
