heh, I did the same thing with mine, well except for the painting It looks really nice though. I did swap out all the brown/tan interior pieces minus the seats and the floor mats, this was all spread over 2 weeks or so as I was collecting the pieces.
First day of the swap: change the door panels (15 minutes, tops)
Second day of the swap: change the dash, carpet and random interior pieces in the front (took 8 hours by my self)
Third day of the swap: change the rest of the interior pieces in the rear of the passenger area and the rest of the front interior pieces.(5 hours)
4th day: remove old door inserts from old panels and new door inserts of new panels and switch them...(hour, had to wait for the glue to dry)
if want any tips on getting the rest of that stuff out let me know
