I have a question and a problem. I'm doing a 73 restoration that was an auto. I'm changing it over to manual with 72 round top carbs and intake manifold. It appears the carb linkage arm that runs from the firewall bracket to the intake manifold are different lengths. I looked on the micro fisch and it does not indicate that they are different. The mfg date on my 73 is 3/73 not sure the mfg date on the 72 (I only have the engine & trans). Attached are two pics. The yellow one is the original one on the 73 connected to the flat tops the silver one it the same linkage arm attached to the 72 round tops. Note the spacing between the firewall bracket and the upright angle bracket on the linkage arm. Comments, suggestions, resolutions greatly appreciaated.
Thanks
