I AM NEW TO THE POST LOOKING FOR A SIDE SKIRT FOR A 98 SC300 DRIVER SIDE

HAVE ANY ONE DONE A MOTOR SWAP BETWEEN TC SC400 AND THE SC300

I have also a 98 SC300 but I never tried swapping with any auto parts to other model of Lexus. I suggest you can read some auto topics like the Car Geek (http://innerautoparts.blogspot.com/). You can get some ideas there.
