I'm reading the factory service manual and see that the bolts all have numbers beside them in the component diagram. as an example the front sway bar endlink bolt is 52 (530,38) and the bolts that hold the swaybar bracket to the frame are 18 (185,13) What I can't figure out is what those numbers mean and can I identify the size of the bolt from them somehow? It's not a part number as far as I can tell as 9011910765 is the part number for the endlink bolt.
