kickdown Rod extension?

I just did this 4 BBl conversion on my 318 Duster w 904 Trans. I used the edl #1481 adapter on a 1405 carb and with a 1/8 aluminum plate 11/2" x 3" which added length to the throttle adapter. Before I added this piece I measured from the firewall where the kickdown linkage was at idle and that's how I came up with the extension I made up. I also added a few holes in the alum. plate for the throttle stud and to secure it on the throttle adapter. Worked out perfectly and tranny shifts the same. Make at least 2 holes to secure the plate to the 1481 adapter.
