Lokar flexible braided stainless dipstick with machined aluminum knob. Fits 1979 and earlier small block Chevy. Dipstick pushes into block on drivers side. Length is 12” see pics. Quality parts and service for over 50 years.
The only reason I am giving it a four star review is because it's very difficult to read when the oil is clean. Aluminum with oil on it is very difficult to see, full or low. When the oil gets old it I am sure it will be much easier.
