Thanks brammer thats a great help mate......soo today
I called powerflex head office not to complain to to find out what the issue was,the guy there was a great help and said he would call me back within the hour.
45 mins later he calls me back, turns out a few years ago at powerflex there was a fire , after the damage was done some bushes were made to old spec and part numbers etc crossed and mis made . Turned out he had a 3 door cosworth in there yard so he measured the bushes on that car and said my findings were correct the bushes i was sold are wrong.
He also said they didnt stock these larger bushes and as i found out a cock up on there site they are re making them and posting me a set for freeeee
SO anyone with a 3 door who wants to replace there old ones give them a call as there re making them within the next 2 weeks
