clunking under driver side

[mrbamcclain]

I've got a feeling under my left foot under the floor board. What is the most common part that could be? I was thinking maybe endlinks or the sway bar?
Two other questions. To remove the factory strut mounts to mount an fstb do I need to have the front on stands? What kind of drill bit is needed to remove them?
I've got alot of hard shifting that I'm figuring has to be the motor mounts. How much on average would it cost to have all 3 replaced? I know I can get the mounts online. Is it hard to do myself?

Could be a sway bar bushing or a subframe bushing.

You don't need to jack up the car, and should be using a spot weld drill bit to release the factory alignment plates.

To pay a shop to do all three mounts would probably be about a $100-$150 job. To do them yourself is not that hard, but if you've never done them before expect it to take a while.

My drivers side plate has already been drilled for an alignment, but my passenger side needs to be drilled. Where would I get that drill bit? I went to Autozone and they looked at me like I was crazy. The drivers side plate won't come off. I took all the nuts off and raised the tabs but it's on there like something else is holding it. Any ideas? I didn't want to force it as I didn't want to break anything.
