Need help on correct linkage.. who makes it

Your photo is correct for a '64-6 model (2bbl in this case). The 4bbl is very similar, except the upper bell crank and forward rod is different, along with the accelerator cable bracket (which is a separate piece '64-6). Looks like you have an aftermarket intake and carb. Most times you need to do some modification to make the stock stuff work. Now, using the '67-up setup, you might be able to use it if you have enough clearance to do so. There again, you may have to made some mods to make it work correctly. Some intakes and carbs have different bosses and connection points.
ok great, then it must have been a 2 barrel car to begin with then the after market and then the try for retro fil. i think the kickdown will still work, just need the 4 barrel throttle bracket conversion
