To replace the windshield on a Lexus SC400, first, remove the wipers and carefully detach any trim or molding around the windshield. Use a windshield removal tool to cut through the adhesive, then carefully lift the old windshield out. Clean the frame thoroughly, apply new adhesive, and position the new windshield into place, ensuring a proper seal. Finally, reattach the trim and wipers, allowing the adhesive to cure as per the manufacturer's instructions.
The SC300 and SC400 (but NOT the SC430) are the same body and many of the parts are identical. I do not know for certain, but there is a very good chance that a windshield that fits an SC300 will fit an SC400. They might even be the same part.
All I have heard is to replace it.
