1978 Other Volkswagen Models

Hello I know these busses well" if you look strait down at the base of the distributor you will see a clamp " part of the clamp is held to the engine by a 13mm nut. The rest of the clamp is clamped to the post portion of the distributor by a 1in long bolt the head of the bolt is 10mm loosen both of them. And then give it a slight twist & that thing will pull stait up out of there. Ok" good luck if you have anymore questions get back to me.I hope this helped".
