Driver side valve cover..?

[Mach This]

I have done just about everything to get this thing off. All the bolts are off of the hydrabooster, and it pulls out but not all the way and I dont know why.

The studs on the booster itself wont pull out far enough to come out so I can move it aside.

Here is a link to a guy that pulled his valve covers off and it looks like he didnt even touch the hydrabooster!! Is there some trick?

I have searched the registry and can't seem to find the info I need...Any help appreciated.
