    67 correct length 2"exhaust clamp at X member

    Where can 1 find the correct length 2" exhaust clamp that goes at the center hanger. The ones I received with my CC complete kit are too short and will barely allow the nut to be started. You cannot install the ground strap due to the U part not extending thru the holes of the guillotine section far enough. TIA

    Al,

    The 1966 & 1967 AIM's list 3853726 as the part number for the U-bolt. GM # 3853726 was also sold over the counter until Oct. 1970 and then replaced by GM # 3949198 in Gr. 3.708. The guillotine clamp, GM # 2385666, was apparently not sold over the counter.

    The U-bolt on one of my aftermarket C200 (8605) 2" clamps (not for sale) measures 3 1/16" (inside radius to ends) and the thread length measures 1 3/8". The guillotine clamp measures 1 9/16" (see photo).
