1966 dart linkage for four barrel

Scottsman - the oem 4 bbl linkage parts are made from unobtainium. Having said that I did locate the correct parts to do my car, but it was a long time coming before I found them, after 5 + years of periodically searching -

I would use the later model 4 bbl linkage and kickdown assembly from a 340 set up. The throttle brackets are being repopped. I would check with folks like A&A transmission or mancini racing. They should be able to point you in the right direction. By the way, the linkage from the upper bellcrank (including the bell crank) down to the trans is the same as any 318 2 bbl. What you will need is the repop throttle bracket and the rod going from the carb to the bell crank, and the rest of the stuff from a 2 bbl 318. I am not sure what model edelbrock carb this - as to whether it is set up for mopar linkage or not. Edelbrock sells an adapter for their carbs used on mopar apps if you need it. You will also need - for lack of a better term - a kickdown/throttle stud that attaches to the carb. Look at any carbureted later model mopar - they will have one.

You wont have to shorten the driveshaft until you install the 8.25 axle.

You might think again about putting disc brakes on the front, your call.

Good luck with it.
