This is a good start. However, you won't need the crossmember and trans mount as the ones you have will bolt right in (and the mounts for the manual crossmember are INSANELY expensive compared to $20 for the other one). However, you DO need the torque arm insulator that holds the arm to the tail of the trans. This should probably be bought new, or tell the guy in the yard you need everything that goes with the trans including this mount.

You probably won't find a 5-speed MEMCAL for your car either, as most of the ones in the yards are more than likely older cars that don't use a MEMCAL. And the ones in FWD vehicles won't work as the ignition tables are WAY off.

Someone forgot that you also need the flywheel and clutch. Without those, you're not going anywhere soon. The flywheel MUST be for an internally balanced engine or you're going to shake the car apart.

:edit: While the trans is out, also replace the rear main seal and rear cam seal. You don't want one of these to be bad and spit oil all over your clutch, especially if you don't already know how to drive a manual trans.
