You can purchase the brake block off pieces, but it is so easy to use tin snips, a hole punch made for leather, and some thin aluminum to make your own. It is just an annulus with five holes for the rotor fastener heads to stick through (you don't sandwich this piece. Drill five 1/8" holes in the rotor and pop rivet the aluminum piece in place. You can remove it when it becomes rotor replacement time by drilling the rivets, and reuse the plate you made.

And of course remove the backing plates. But if this is a street driven car only, you really don't need to duct any air to the brakes - just don't brake so much, and use a lower gear coming down curvy hills to keep the speed down.

Good info, Walt. Thanks!

I'm going to replace the brake lines and flush/bleed as a first step. The 993/964 air deflectors seems like they are easy and cheap enough.
