Can someone tell me the difference or show a good comparison picture of the actual difference on the throttle bracket for 4B for 383/440. Going through linkage and brackets for kickdown. Also for the lever I have seen straight and curved variations of the 2465413 lever? Was it a model/plant/year specific thing of just a different vendor thing. Thanks,

I want to say they are the same then someone will correct me ,

so here is a

I was thinking that the actual bracket was the same also, the rod going down to the transmission is the only difference.

They are different. Both mopar parts manuals and the reproduction crowd have separate listings. The 2 barrel are also different. Where the throttle clamp is positioned is the difference. 2 barrel have a longer extension to move the cable to the center. So for the subtle difference in the 4 barrel brackets:

I really do not think it is easy to see in the reproduction pictures, but I do think I figured it out for the 67-70 brackets. Attached are some pictures. From original pieces the 383 finger at the front of the bracket is narrower than the 440. The bracket extension for the clamp for the throttle cable is angled up more and the slot the cable clamp goes into runs along the outside of the bracket. On the 440, that extension is more horizontal, and the clamp is positioned slightly inside. This makes sense since the 440 is wider and there for the cable would need to move inside. The 4 speed brackets match, but the stud is not present, just a hole.

As far as the lever, I show both. The position angle is identical and they have the same part number as best I can tell. Either type I have seen on all sorts of motor SB, BB 67-70. So who knows why?
