Looks like you installed it correctly!. A couple comments about the Lokar cable though and the transmission operation. You need to make sure of 2 things:
1. Transmission kickdown return. Because of the cable design it can get "bound-up" from 1 cause or another (stressed cable, not even spring action in the kickdown lever, etc) and delay returning when letting off the gas, or get hung-up and not return all the way. Half the time I've seen this happen and the other half not. If this is happening you can add a light return spring down on the kickdown lever. A good mounting point for the spring is the boss where the column-shift linkage bolts to.
2. Transmission kickdown throw. You need to ensure that the throw is correct on the kickdown lever. The most recent install I did (Edelbrock carb, 727 transmission) the kickdown lever was the shortest style (fyi there are several styles of different lengths). Even though it was the shortest lever it was still too long for the Edelbrock carb. With the kickdown lever all the way back at WOT, with foot off the gas, it wouldn't release the lever enough, so the shift points were VERY late. I slowly adjusted the cable back little by little, and by the time I got somewhat reasonable shift points, the car would no longer kick-down when I floored it. I had to remove the lever and drill a hole closer to the bracket mounting point (there was actually already a small hole there) to allow for greater throw.
Best of luck, this is a good system, it just needs some tinkering sometimes.
