Suspension question.

[thatsnninety5]

On my rear suspension of my car as many of you know the v8s have the horizontal vibration damper. I need to know the bolt size for the plate to frame. Ive saw that you can get kits on places like LMR or Americans muscle for all the bolts for the whole thing but all I simply need is the bolt that goes in the frame that connects the plateuu to. If anyone knows the specs of it so I can pick it up at a local advanced auto that be much appreciated. Below is an image of what I am talking about

Careful installing it if the captive nut is rusty you'll want to chase it with a tap, because if the captive nut breaks off you're gonna be drilling all the way through the frame rail to put a nut on the gas tank side.
