You've gone from a manual transmission to a new TH400, Powerglide, or 4L80. And you've removed your old clutch master cylinder to keep the weight down. But now you've got a nasty hole in your firewall. Dress it up with the PHR Billet Clutch Master Cylinder Block Off Plate.
Made from 6061 Billet Aluminum and including all hardware, it's a simple installation that takes only a couple minutes to install and finishes off the engine bay nicely. It's the details that make the difference.
Fits 1993-1998 Supra and all SC300.
