I bought a couple of old Mopar AFB's on Epay with the correct tops and mounted them on new 9606 AFB's and they work great. You have to look carefully to make sure you get the correct tops though.
Now I've got AFB parts everywhere. I used new carbs on this build so I got tight throttle shafts. Next time I'll just rebuild a set of old Mopar AFB's.
