I have the red polyurethane replacement bushings for the dog bone strut which I purchased from the Fiero Store. I've gone back and read all the threads I can find on what bolts to use because of the slop when the original bolts are used. I'ts been mentioned a couple of times that a larger O/D bolts is needed. The original bolt is a 10 9 bolt. Am I correct in assuming that you have to go to a #11 metric or a 7/16 standard bolt? And then drill out the hole in the mounting brackets to accept the larger bolt?

The 10.9 that is on the head is the hardness of the bolt. It is a metric reading and translates to grade 8 in American.

You could replace it with a larger 7/16th bolt. I have always used the correct factory bolt and have never had one come loose.

I went that route, no more clunking noise. Some folks have used the old bushing in the new poly as it has a serrated edge.
I posted lots of information for everyone to use in my "rebuild a dogbone thread".
