Hello all, I gota question. I have a Toyota Tacoma and I am looking to buy a 10K to place on the bed rail right behind the rear window, I take it the coil must be above the cab, but how much? Measured it out and it looks like I need to clear 23", should I get the 22" and add a spring? And What is the length of the whip on a 22" or 27" ? finally can the 10K be tuned (like a firestick) ? Thanks everybody.
