Time to get yet an other throttle cable, I am sick of them breaking/fraying on me. the last few that I bought were the universal kits from o'reilly. Now my friend who is in prison is a gear head from hell, so sadly he can not help me do any of this, just give me advice from time to time. He put a Lokar cable on his 66 F-85, and its been there for over 10 years now and still good. So I am wanting to get one

My questions are do I get the 24" or the 36"? I am planning on just the univeral one that they have.
And which bracket do I get for it?

Anyone else use Lokar throttle cables?
