shocking...

while under my 94 rodeo (4wd, 3.2L, ~130,000 miles) trying to replace the starter, I noticed that the driver side shock's bottom retainer bolt is gone. Seeing as I need a new one could anyone here tell me what size bolt I will be needing?

Not sure what size, but a good parts store can look-up shock absorber mounting hardware by application.

then I shall ask my friend who works at an AutoZone. Thanks.
