In-car balancer replacement

I was about to install the harmonic balancer with the engine in the car, when I noticed a notch carved into the bottom edge of the radiator panel , lining up with the middle of the crankshaft. This must have been forethought by GMH, as I sure can't swing a BFH in the gap where the radiator sits, but nowhere in the manual does it mention this. A 18" piece of 20mm shaft in there should make the job easier (after cooking the balancer for a while to heat it up). Apart from balancer access, the only other reason it is there is for a hand crank to start. I have had early Chevs with the special drive on the pulley to take the hand crank, but never seen a Holden with one. Anyone else have this notch, or is that why my FB is "Special"?!

It is there to allow space for the removal tool I believe. There was never provision for handcranking.

The grey motor industrial engines came with a hand crank option (… though no bodywork for the notch).
Hand crank, magneto and mechanical gauges allowed simple, no battery operation on stationary engines, cement mixers etc.

Nothing wrong with the old balancer, just the timing cover seal.
I used a removal tool which I made, and didn't need that clearance on the front panel.
