mk1 golf driver big bumpers

hi i am looking to fit big bumpers on my mk1 golf driver. ive found a pair of a mk1 cabby and not sure if they would fit could someone give me a bit of advice thank you

Bumpers should fit fine - unbolt the old, slide them out and refit the big ones.

You will however need to fit arch spats and sill trims if you are going big bumper
