S2 Side panel fit - advice please

Have a S2 and the side panels aren't a good fit to the frame.
The fit seems to be getting worse - to the extent that 1 panel came off last year (no significant damage thankfully)
Being honest the panels are a bit battered & bruised (scooter hasnt been restored) - but would prefer to keep original panels rather than buy new panels and have shiny paintwork.
The panels lock in position at the back handle end - but you can almost lift them off the front end.
Panel rubbers are 1 year old.
Satisfied that the frame is good - the opening at the bottom between fuel tap & the panel clip is consistant with other scooters
Looking for some advice on techniques how to improve the fit. I've tried tweaking / bending the panels a little - but without a stratergy I'm possibly making them worse not better.
