"Back in the day", that was a pretty common failure, more so, it seems, once VW moved from the big roller pedal to the little roller behind the flat gas pedal. Because of the water (and slush in the winter) dripping off of the driver's foot, the hinge at the bottom of the pedal corrodes. The lower half of the site is a pot metal casting and usually corrodes to death, rather than rust - the pedal part rusts, instead.
The first step is to try installing a repair kit, as you have ordered. Usually that'll give you quite a few more years of dependable service. Usually, once it goes after the first repair, it is usually time for a new pedal cluster because the casting corrodes beyond repair and you're, ahhhhhhhh, cooked.
You could spring for a new, late-model (1970) pedal cluster to truly cure it, but try the repair kit first. That way, you don't have to crawl under there for all of the hassle of clutch cable/pedal swap.
Oh! And make sure the little arm of the small roller doesn't have a lot of sideways play in it - you may need a new one of those arms, too.
