    GM
    C/K Series

    (!) Requires the use of stock SB Chevy clamshell mounts for this application or their aftermarket equivalent (!).

    The combined use of these mounting brackets and related Hooker transmission swap crossmembers, will allow installation of an LS engine with a GM TH350, TH400, 700R4, 2004R, 4L60, 4L65, 4L70, 4L75, 4L80 or 4L85 automatic trans or a T56/T56 Magnum manual trans into any 1973-87 GM C10/20 pickup.

    Hooker application-specific LS swap engine mounting brackets remove the installation guesswork and compatibility uncertainty that comes with using universal/adjustable swap plate mounting methods. These brackets are designed to achieve optimized component clearances and drivetrain/U-joint operation angles in this application when used in conjunction with the Hooker p/n 520-12646HKR transmission crossmember, 520-2334, 520-2335 headers and 520-42537, 520-42538, 520-42539, 520-42540 exhaust systems co-developed for the '73-87 C10/20 application.
