For the 'front' mount (on the front of the engine, passenger side of the car):

1. Remove the two bolts holding the motor mount down.  Take note of any
spacers underneath the mount.  The two bolts should be 13mm
2. Place a floor jack under the oil pan and raise the engine up until you
can get a clear shot at removing the through bolt.  The through bolt should
have a 15mm head, and there are exposed threads peeking through the other
side of the mount. I recommend you spray some penetrating oil like WD40 on
the exposed threads - it helps removal greatly.  After you have the through
bolt out the old mount should come out easily.
3. BE SURE that you have the new mount going in with the correct side up.
Most Mopar mounts have the top marked but I have seen some which don't!
4. Installation is the reverse of removal!

For the 'side' mount (directly under the radiator)

1. Remove everything in the way of the mount bracket.  The lower radiator
and heater hoses clip into a plastic bracket on this mount. There may also
be a wiring harness clip for the hall effect, temp gauge, and alternator
harness on the bracket.  Getting everything out of the way helps greatly!
2. There is a through bolt and nut holding the mount to the bracket on the
core support.  Remove the nut and try to work the bolt out.  It may become
necessary to rock the engine back and forth to get the bolt to come out.
3. With the bolt out, the engine will tip downwards slightly.  This doesn't
hurt anything and will not impede getting the bracket off.
4. There should be three 18mm bolts holding the bracket on now.  Two will go
directly into the block while one goes to the transmission.  One you remove
these the large metal bracket with the rubber isolator will come off.
5. Notice how the old isolator is installed and make note of which side is
the top.
6. The isolator is held in place by bent over metal tabs.  Use a pair of
pliers to bend the tabs over on one side and push the isolator out.
7. Install the new isolator and bend the tabs up to lock it into place.
8. Put everything back the way it was.  It doesn't matter which way the
through bolt goes through the mount.

    The only mount not available is the transmission mount, which is
different than the others.  I have no experience with headers on these cars,
but I know the stiffened mounts will definitely reduce the amount of travel
the engine has.
    For added stiffeness, some people has filled the openings in his mounts with
little triangular wood blocks to make sure that they don't flex >at all<.
