Having just bought an 1988 16v which has big bumpers fitted ( I say fitted ), which i know weren't standard back then, but whoever put them on i don't think has changed the side small bumper brackets to house the big bumper...
Is it as simple as taking big bumper off, replacing side brackets from small round ones to the rectangular big bumper ones and putting big bumper back on again?
Mine has big bumper fitted but these brackets.

Thinkin these should have been fitted when they lobbed the big bumper on the car....

Do the old round small bumper brackets just unscrew/unbolt and big bumper ones bolt straight in their place, or is there even a conversion bracket available?
You might say just put small bumper back on but the fogs and everything are wired in so seems a shame.......
