The chrome comes off much later... Get into the back seat area, remove the well liner.. There will be a series of bolts with special washers.. Remove those & the top fabric will come free from the body... now remove the rear trim panels (they would be door panels but) behind the panels you'll see the top cylinders are retained by a bracket & a clevis pin.. Disconnect them & leave them with the car, or remove them with the pump & lines as an assembly... Now you'll want to notice there are two 1/2" holes in each side of the top frame which lines up with holes in the body.. these are so you can line the top assembly back up easily.. Loosen the bottom bolt a couple turns & remove the other two bolts per side, then lift the top off the car... Easy..
