Help confirm where to fill top reservoir please.

Factory service manual would be your best source of info, BUT IIRC just under the inspection hole, and rubber gromett is most likely the inspection hole. Pretty sure the center bolt clamps the resivore to the pump.

I seem to recall seeing a how to on top pumps

Thanks for the quick response. Hey did look in my service manual, and in the convertible section it went into care, up/down, and top adjustments; but nothing that I could find on fluid maintenance.
So, if I’m reading your response correctly, the inspection/fill hole is the rubber grommet?

thank you again!
