904 trans shield

I use the CSI shield on my 65/904 it fits with [some interference]...some grinding required, but very little. I also modifyed it for band adjustment while in the vehicle. I also rotated the "strap" to keep it out of the way and easier access. If this is going into a race car, may I suggest drilling holes throught your fire wall for socket clearance to get at the always tuff bell housing bolts! The shield makes this job even more difficult! If you use allen headed 3/8 X 16, and and extended allen socket, the holes do not have to be very large!
Just my thoughts.
