I bought a truck that had a Lokar throttle cable.
I almost wrecked it on the way home do to a stuck throttle. The cable had sawed though the sleeve and was binding up. I put an OEM cable back on.

Rather than fight getting a solid kick down linkage to clear headers, I installed a Bouchillon KD kit on my '68 V100. It is heavy duty compared to Lokar and has the correct carb linkage to KD lever ratio.
