Detroit Speed Clutch Master Cylinder BracketThis Detroit Speed, Inc. bracket mounts the GM hydraulic clutch master cylinder to the firewall of the 1970 1981 F Bodies. The bracket correctly positions itself by mounting between the firewall and brake master cylinder or brake booster on power brake cars. The firewall will require a clearance hole for the clutch master cylinder to pass through once the bracket is in position. Attributes: Brand Name: Detroit Speed Archived GTIN: 00090127172612
