Dam near impossible, to remove the clutch master cylinder had to crawl across the car from opposite side, lay across motor and reach inside of fender and around brake booster .Working blind, just feeling around by hand.Not a job for old men. Finally got it out, but what a chore! Not looking forward, to replacing with the new one. Looking back on it, I should have rebuilt it in the car . I think that would have been a lot easier.
