So while finishing up my transmission re-fresh, I managed to snap one of the pan bolts while torqueing. I decided to order all new hardware and this is what arrived today. The new hardware is no where close to being right, but every part diagram I've found shows 9979-60-620 as being correct.
Anyone know what the number for the actual bolt is? Really want to finish this up and get this thing back in the car.
9979-40-830 is something like this
99 tells you its hardware
794 is what kind of hardware, a bolt, nut, screw, and what style it is. there isn't a chart, but often if you put the number into the internet, you can get a picture
08 is M8, and Mazda uses JIS standard, so an M8 is a 1.25 thread with a 12mm head
and then 30 is the length of the threaded part
if it is not a normal JIS fastener, then it would get a normal part number
Was able to confirm through the dealer that the '93 parts diagram is wrong and that the part # is correct in the diagrams for '94 and onwards. Guess I'm going to have to start cross referencing with later diagrams on Amayama lol.

That's actually really cool to know the breakdown of the part #. Like when I learned the difference between all of the prefixes like FD01 and FD04 (which I have since forgotten)
