Stock '69 289 throttle linkage?

Here's how my '72 looks. When I saw this, I copied it on my '68.

Always loved the 4100s. I'll bet that and the stock 4 barrel intake produces better torque than the high rise and Demon. Today I tried the '68 lever thing on a '77 and found out that on the early bell crank, the inboard leg is bent back about 30 degrees and the legs on the '77 are almost parallel, so they are made to work together. I'm not swapping the bell cranks. There's too many hurdles too find way to use the lever linkage, so I'm going some other way. I think the best thing is an extension on the carb's throttle lever that places the ball stud above and slightly behind the throttle shaft. Also it will be as far from the throttle shaft as possible while allowing full depression of the accelerator to fully open the throttle.

FYI - I had to make the link from the carb to bell crank on the '68. Used a wire hanger to make a template and then extended one of the original links to match the template.

The '68 is fun with the 302, but the '72 is stoked to 347 with dart heads and a big cam. Even more fun

In Jd's pics too, you can just see the firewall mounted bracket and attaching bolts.
Good pics.

Your right. The lower picture shows the little L bracket still bolted to the fire wall. Jd's extra long throttle rod had to be fabricated to reach the early bell crank. To switch to the late throttle linkage you may want to get a late type bell-crank so the rod would be long enough to reach the ball stud on the carb.
Non of this helps my original problem. To deal with the lack of fine control of the throttle when it begins to open, I'll have to fabricate a new place for the ball stud. It seems the carb makers put the ball stud in front of the throttle shaft to make vehicles seem more responsive. They sure weren't thinking about 4-wheelers trying to finesse their way through tight situations.
