Swaybar question....

[ManaMan]

After taking my motor and gearbox out to change the clutch/pressure plate/flywheel and assorted bearings......I was finishing the install, when it came time to the sway bar, the bolts that attach the bushing cover to the body were missing. I looked high and low, and still can't find them. I am hoping that someone here can tell me the bolt size to buy. I tried the Porsche site, but their diagram schematic for my car...'77 930 is not working. Anyone know the size bolts I need? There are two for each cover that attach to the body.

Thanks in advance, today would have been nice, for a good drive...hopefully next weekend.
