This twin-tube style front core support crossmember for 1963-66 C10's replaces the stock crossmember under the core support for a cleaner look. Installation is straightforward, as it bolts in between the front frame rails. The radiator mounts on top of the new crossmember, just as with the stock unit. (New radiator lower mounts NOT included).
