I think I have finally found the clunking issue in my car's front end. It feels like the whole engine is moving forward when I brake. I look under the driver side and there is no bolt under the motor mount. I already have new mounts but I need to know what the bolts are. Thanks!

The bolt is sheared off and the hole full of dirt.

Amazing, thanks so much! Is this the same bolt for the top of the mount as well? So 4 total? I would like to replace all 4 mount bolts.

The top bolts should be taller than bottom's,,

So the front shock bolt is the exact same part as the bolt used for the engine mounts? It looks like the shock bolt is only threaded partially while the engine mount bolt is fully threaded.

NM. ECStuning had everything I needed. Order placed.

Not that sure about that..!,,

but as i believe; no need to be full threaded for top bolts..!, bottom's should..
