Lokar Installation

There are several kickdown (Throttle pressure) levers out there. Is there a measurement from where the lever mounts,to where the cable mounts on the lever? Factory 2 barrel is longer than 4 barrel. I had 2 that were the same length, but the location of the flat in the D shaped hole that goes on the transmission was different . Swapping the levers made all the difference. I would be sure it's what you want before spending that kind of money. Since you are going after market , and if there is a measurement for the lever, why not just use yours, and drill at the correct length?
