I have a 1989 RS that I will be installing front struts. I know this has been posted before but I can't find it. What is the torque specs. for the bolts that hold the struts to the hubs? Thanks in advance.
I believe GM recommends 120 ft./lbs, but I'm not sure. I did mine at that much. Never had a problem. Keep in mind the rotation of the threads on top of the mount.

I got 203Ibs from my 1989 GM shop manual. Where did you get yours?

Different year manuals recommend different torques. Newer f-bodys had a lower torque specs for some reason. As long as its between 150-200, it should be fine. They're crimp nuts, so they wont fall off

Chiltons... says 125 ft.lbs., followed by 120* turn, not to exceed 148 ft.lbs. (which apparently calculates to 200 Nm...), but you're talking ft.lbs., too, right? I dunno... 125-148 seems plenty tight... That's a heck of alot of diff between the 2 manuals though, ain't it?
I used the 203 figure - actually probably more. (3" pipe x a lot of pressure = more than 203) I messed up the threads on the bolts so I got new 5/8 grade 8 bolts, washers, and nuts and used those. I think the knuckle bolt is some sort of metric thread that no hardware store near me carried so I used standard. If I have any problems I'll post (as usual)
