True, the database will never know what day Frank the fender guy on line 2 ran out of BS bolts and changed over to UN.
But, in our database each manual
will have it's own "boot notes" which could include information like such-and-such changes happened... this year, in such a month, with such a VIN, etc.
That information is available with one click wherever the name of the Replacement Parts Catalogue (RPC) appears anywhere - in the index, on the page with it's errors, etc.
And meanwhile and most importantly the database will tell you what part is SUPPOSED to be used there! And perhaps also that the drawing is wrong, or what's missing, etc.
