Fitment & Compatibility
Identify the installed brake conversion before choosing this hat for Chevrolet C10 and C1500 1963–1997 brake conversions. The offset, center register and attachment hardware must agree with the rotor and hub in that assembly. Select the rotor and attachment hardware separately for the documented assembly. Follow the installation drawing for engagement and clearance at every mounting point.
