Front 2 and rear 2 are obvious (under the hood, and at the rear of the engine bay).

There are 4 others too, right? Locations?

I have a bit of a clunk under load / direction changes (tabs are TIGHT, control arms are too, as are all ball joints) - Many of my bushings look like they are in sorry shape, but of the 4 body to frame bolts I gunned down, all 4 were loose and it improved the light clunking. Were are the other 4?

There are a total of 12.

2 in the trunk going vertically into the front shock towers
2 in the center going horizontally inward near the drivers and passengers knees/shins
2 in the center going horizontally inward just forward of the seat belt receiver
2 in the center going horizontally inward mounting the seat belt receiver to the frame
2 in the engine bay right at the firewall going vertically into the rear shock towers, (also holds down the big black metal bar going across the back of the engine/transmission)
2 In the engine bay in the frame almost at the bumper going horizontally inward from the body tub

They are all M10 bolts. The 2 in the front shock towers go into welded nuts. The 2 going into the seatbelt receiver go into welded nuts that are fine thread (1.25 pitch). The rest go into captive square nuts. All but the seatbelt receivers are the special pointed M10's (to help with alignment).

I believe the 4 vertical bolts are M10x40 where 6 the horizontal ones are M10x30

EDIT: Just looked on the DMCH website. It said that the 2 holding the seat belt receivers were 7/16" X 38MM bolts??? I'd double check that because that doesn't even sound like a real bolt to me, unless it's a 7/16x1.5" fine thread bolt. When I did it I just assumed they were M10x1.25 bolts. Hopefully someone else can chime in.

This is correct - the seatbelt anchor bolts to the frame are 7/16 Imperial, so slightly bigger than M10.

Then go to picture 6 of 11 and there in picture 6 are three of the twelve body bolts.
