IMPORTANT - PLEASE READ: This special order 17 degree upward angled design is only recommended for installations that cannot run the standard production 3021/3023 model with the highly improved original 6 degree design. Running the standard 6 degree design  promotes a vastly improved appearance, especially since it matches the 6 degree upward angle of the engine. The brake fluid level inside of the master cylinder is also at a lesser angle in the 6 degree 3021/3023 model, which helps to minimize brake fluid seapage from the master cylinder lid. Being a special order model of limited demand, please allow for up to a 2-3 week lead time to produce this order from the time your order is successfully placed.
