You need to invest in a Grade 8, or Grade9 (F-911) bolt, along with putting good grade 8/9 washers on both sides and really crank down. Be leave it or not, its not the BOLT that is holding the upper control arm/joint on, its really just being squeezed. Also, make sure you sand down any paint thats on the out side and inside of the mount to make sure you get a good SOLID mount. And if you used your stock bolts...witch are torque to yield... thats a big no no, Alot of people that use this type of join, think they have problems because they crank down on the stock bolt...getting it "tight" but its just stretching even more. Biggest thing is getting enough clamping force to hold the Joint and to keep it from "popping".

On our GT500 we used 1/2 and 9/16 and torqued them to 95 and 165 to 175ft/lbs respectively.

You can find the F-911 bolts at http://www.allensfasteners.com/search_results.asp?txtsearchParamCat=73 Along with Torque specs. Good fast shipping...they are out here in Cali too.


I'll update this thread with Photos, as soon as I can.
