Renault Megane Convertible - aerial replacement?

I HAVE A 1999 ( V REG ) YOU CAN TAKE OUT THE AERIAL ASSEMBLY WITHOUT MOVING THE HOOD HYD: PUMP. TAKE OUT THE REAR LIGHT( 4 NUTS )
REMOVE THE BOLT RELEASING THE AERIAL EARTH STRAP ( ABOVE AND BEHIND THE PUMP ) BELOW THIS IS A SMALL BOLT ( 8MM SPANNER ) THIS IS ALL THAT HOLDS IN THE AERIAL ASSY: IT IS A PIG TO UNDO BUT IT DOES COME OUT.TAKE OUT THE AERIAL ASSY BY PUSHING DOWN ON THE TIP OF THE MAST. (IT IS ONLY PUSHED INTO THE RUBBER GROMMET ) THE GROMMET STAYS IN THE WING. THE AERIAL WILL NOW COME OUT COMPLETE AFTER UNPLUGGING THE CONNECTOR AND UNSCREWING THE AERIAL LEAD.
TO REPLACE THE ASSY:I FOUND THAT IT IS EASIER TO SCREW IN THE SMALL BOLT THAT HOLDS IT IN THRO' THE FRAME ( FROM AERIAL SIDE ) LEAVING ABOUT 12MM STICKING OUT. ( I REDUCED THE THREAD ON THE END FOR ABOUT 5MM LONG SO I COULD LOCATE THE NUT ON THE BOLT. IT WAS STILL A FIDLY JOB BUT I DID IT.
