Calipers are different between the A & E body line of cars.

73 - 76 A Bodies use "SLIDER" type of calipers.
70-74 E Body, 70-72 B body cars use "PIN TYPE" calipers.

Gotta know what type caliper the op is using before telling him what type hose to buy.
Then also gotta know if mounting the calipers towards the front of the car, or the rear.
Lot's to find out.
