Hello I am writing you because I read most of your posts and think you can help me because I have a problem with spring shaft and especially their finding. In particular, his head pulled my (Saab 93 OG Aero B205R) sent her into a factory for grinding, porting, changing erasers, cleaning of valve well here but it turned out that need replacing spring shaft. When you first started looking I found that not a second that I read about one who put on Volvo but I think that for me they will not fit because I am head of T7 and they are T5. So far I've made exhaust manifolds, the whole system intact and generation of 3 inches. I hope not bother you, greetings from Bulgaria.
