After pouring over the AIM, AMK catalog and my bolt bins, I have come up with a decode for the front end bolts for 69 at least. I started this over on TC. Anyone care to comment?
Front end bolts decoded - corrected
The front end is held together with many types of bolts. Part numbers are listed in the AIM. Pointed means the earlier style with the cut ends, not the later ones with threads all the way to the end. I will try to describe them below:
