Wherever you go, there you are.
I used a Dremel with a cut-off wheel to trim the plastic on my seats. Have to watch the speed and deal with thermal melting of the plastic, but overall decent results albeit slow. I first scribed a line to follow. I wasn't sure how to get a guide clamped to the uneven topology of the plastic in order to use anything else?I finely cut 2 inches off the side skirts on the front seats to allow rotation withing raising them. I took me a while to find the right tool by experimenting with different saw blades on thin sheet of plastics. Some of them were disastrous, I finely got one from Makita for thin plastic which gave me clean cut with very little cleanup with a deburring tool.
