Tom, Just because the fws share the same bolt pattern, doesn't mean that they are interchangable. The 280 fw I have also will bolt up, but I wouln't use it either. The manuals say that the 240 and the 300 (616 & 617) fws are different and not interchange them. After running the 616 fw and 4 speed trans behind a 300D turbo for over 2 years, I can say with experence that it works, but isn't right. I did get a quote on a new 617 fw from Europe-$500+. I will probably go that route. What's money between men like us?
Thanks, Tim
