Someone once told me that the hardest part of restoring a mini is removing that split pin so everything else should be a breeze......
Hate to be the bearer of bad news but the brake pedal is fitted in the same way so i'm afraid you will be contorting yourself again.
Unless you happen to be luckily enough to have an 89 onwards mini with the servo, Then you only have the clutch split pin to worry about and the brake ones are in the engine bay.
