Carb linkage and adjustment questions

1965 Valiant, 225/6.
The car came with the wrong carb and the throttle linkage is a bit rigged together. I've acquired the correct carb (Carter BBS) and am about to tackle the swap. Today, I noticed that the linkage arm seems to be at a different angle than the linkage on the new carb. The pedal/throttle rod is more horizontal, and the linkage on the carb is at an angle.
