How to secure washer bottle on car with factory A/C

My 71 has (or, I should say, had) factory A/C. The windshield washer bottle is up at the rear of the trunk in these cars, and secured in place by a rubber strap. The strap hooks to a nice, sturdy bracket where the bottle sits, on one end. On the other end, it hooks over the cardboard divider, which covers the blower fan, etc. Over the years, the hook has really done a number on this part of the divider - it is broken and bent in that spot, now.

Has anyone worked out a clever way to hold the bottle steady, without using the cardboard divider as an anchor point for the rubber strap?

It isn't easy to relocate the bottle to its normal spot, under the front latch panel, because the A/C condenser fan housing gets in the way, and I would have to weld in a support bracket for the washer bottle, too.

I don't know how clever my design is, but it holds the bottle in place for autocross and brisk drives - I took a long black (proper aesthetics are everything :rolleyes: ) zip tie and looped it around the neck of the bottle and affixed it around the brace piece behind the cardboard divider (near the snap). I made sure the bracket holding the bottom of the bottle firmly holds the base of the washer bottle and the zip tie keeps the bottle from flopping one way or the other. Like I said, not a great solution, but its functional.
