about 10 months ago i went to look at a 1200 coupe for sale in a local trader. It was quite a nice car with some good hot up bits. While inspecting for rust i noticed the floor was all rumpled and buckled like some one had taken to it with the fork end of a hammer. he explained that the day he picked it up he was driving down the motorway when a mazda 323 dohc turbo gave him a go so they started racing and some where above 160kph his drive shaft let go about a foot back from the gear box. He said the back of the car flew up about two feet and the front foot of the drive shaft continued to spin and smash into the floor until it fell out and smashed into the rear wheel. mean while the rear end of the drive shaft continued to thrash around under the back of the car. He said he has no idea how he didn't spin or flip but he had spent about two weeks panel beating the floor and it still looked like ####. Since then I always change universal joints as soon as they start to make noise or develop play.
