Do not bother with the rest of the interior....
none of he other bits will fit anyway.
Oh and if you have the Premium Soundpack (with underseat subwoofer
under the passenger side), do check that the bottom of the seat clears
the subwoofer before bolting it down hard into place. If it does touch
then as per my info in the thread on Colt seats into a 454 you will need
some very thick washers (about 1/4") under the front mounting points
from the floor to get the clearance.
PS...remember to disconnect the battery (earth side first) for 5 mins
BEFORE disconnecting the electrical plug connectors under the seats...
or there is a the chance that the airbag/s will deploy ! Once seats
have been connected and fitted/bolted down, reconnect the battery
(positive side first..earth last)...then adjust the clock/s.
