Does anyone have any ideas where I can obtain replacement brackets for mounting curtain tracks to the paneling above and below the main salon portlights in my 1985 E30+, as shown in the 5 photos? Photo #1 shows the curtain tracks above and below the portlight. #2 & 3 show the bracket holding the track. # 4 & 5 show the brackets for which I need to find replacements. Thanks, stangc
