[69 SS 350 5 Speed]

I just had mine replaced under warranty. Looking at the Header Panel Thread, you can do this yourself with basic tools and a little patience. I examined the old part and it appears that they may have been overtightened at the assembly plant because the breaks are all a radial twist which is an indicator that the plastic was overstressed. I asked the body shop tech if he would try not to overtighten them and he said he would be careful. Guess I will see how long it lasts.
