Alpace,
There is a panel behind each wheel in the fender well on KMP SCs. It needs to be braced on the rearmost end or it wobbles and makes an
oil can kind of noise. A small wood block glued in works good. Also look to tightening the arm that holds the trunk open and while your at it check that the hood brace is tight too.
I just finished pulling out the seats and carpet dynamated the interior (None next to the gas pedal, it's to thick there) sealed the aluminum seams and had a boot made for the E Brake with it's hole into the tunnel, it is like frikkin night and day. No more exhaust in the cockpit, 90% of squeaks and rattles gone a way less engine heat coming in.
Have fun
Kurt
