Quick body bolt question (size, etc)
I'm at work right now and running to get some bolts on the way home this afternoon. I forgot to bring one of my old body bolts with me, but realized I have all of you out there to privide my answer 
I know that it is a shoulder bolt and it probably 7/16" in diameter, and don't even want to guess the length. I also assume it's a grade 8. Please comment on correct diameter, length and grade and thread style.
BTW: I have found that Lowes (yes Lowes) sells grade 8 zinc plated bolts and HW at pretty resonable prices. They seem to have a pretty good selection as well. You can get nuts, lock washers, washers and smaller bolts (shorter 3/8" dia. on down) in contractor packs. Saves a lot over diving through the local NAPA bolt bins. They also have a large selection of grade 8 hex head cap bolts, which I really like to use in the engine compartment.

I get all my bolts (G-8 yellow zinc plated) at local hardware stores.
Looks like you want 3"x7/16 coarse for poly/rubber mounts.
The aluminum body mounts are 3/8" thick, so much shorter for these.
Looks like 1 3/4" or 2" long will work, depending on your washers/lockwashers used.
