I don't remember exactly how the tube that shields the starter wires installs. I've got an 85 tpi. It seems like it bolts on the back side of the bell housing using one of those bolts and the other mount to the back side of the starter solenoid? If so I con't figure out how you'd screw on that one. I've had it off for 2 years and can't remember. If anyone can get me a pic that would be great. Thanks, josh
