thermobogs will have correct mopar throttle shaft and you just need the stud for throttle cable/PTK lever which you should have on the eddy adaptor bolted on the 1406. like the Q-jet on the dippy, a mopar q-jet has the correct throttle lever you just need a throttle stud for it.

only thing else you need is the correct tools and knowledge for tuning on a thermobog. I have only saw a couple that someone else had that worked great but I have never got anything out of any I had to bolt on my junk other than a fire.. or 2. but then again I just about burnt my truck up this yr with a holley double pumper. so I guess any carb can do a fire with easy?..
