I was actually making a full list of where all the bolts and everything went add showing what size and all goes where, but after 2 hours and I still didnt have the head off yet I decided screw the pictures and just go the car done. But as for me I just put them all on a magnet tray, but then again I can always remember where every bolt goes, partially because memory and partially because I have built way too many 7m's. As far as making sure they go in the right place a rule of thumb is when you put the bolt in the hole there should be around 1/4 to 1/2 an inch sticking out of the hole when it hits threads but you have not started threading yet. Not all of them follow this rule but most do.
