understanding the parts manual
 

Is there a master list of hardware and where it's used avaible for an S5?
I'm restoring my 90t2 and am going through replacing corroded hardware in various places on the car and have noticed that the same screw or bolt will have different part numbers based on where it's located in the car. 10mm bolts are a perfect example. in the parts manual it is used in nearly every section of the car and in each section it has a different part number. I must conclude that the part number in the book, isn't really the part number, but an item number used during the kitting process during assembly. But somewhere, there must be a list that says 10mm bolt is assigned the following item numbers and is used in the following locations.
I have confirmed this by ordering various different part numbers and looking at them upon reciept and confirming that they are actually the same part, just different numbers. Any ideas. It would be nice to just order 20 of these instead of 3 for here and 8 for here and 9 for here.
Thanks

Ya but Keith,some of the bolts that are listed may be different lengths,even though they are a 10mm bolt.
I Didn't want to take that chance either when ordering bolts for the sway links...But I found they were the same length anyways.
I noticed though that the price is the same,so If It was me,I would just go along with Mazda's stupid Part # scheme.
Oh.also noticed that some of the bolts are of a certain Grade..I would stick to that grade of steel,to assure that nothing snaps under pressure.

Read pages 1-C2 to 1-L2 in the s4 parts manual available online. It explains how the catalog and numbering system works. It is at the beginning of the parts catalog before the diagrams start. I don't think the s5 and s6 catalogs available online have this section.

You're going to spend a lot of money if you buy this hardware at Mazda. The most economical way of buying hardware is to just take the old hardware to a fastener store and have them match it.

It's not just replacing worn or corroded hardware. If that were the only issue, it would be a relativley easy proposition. Since this car was torn down to a rolling chasis two years ago, It and it's parts have been through two moves so a lot of the hardware got all mixed up. I have it all, just hard to figure out where some of it is supposed to go. I've just been ordering example hardware and then matching it up with what I have then tying it to the book. Here is an example. 9986-40-416B and 9986-50-416B is used in two different locations, but it's the exact same screw.
