The first one I did I didn't buy the kit. I adjusted the throttle stops so they closed but not quite enough so they bind. I made up my own progressive linkage uses rods & heim ends. Like I said I sold it before I ever ran it. The 2nd one I built I used a kit from Speed way. I will put it on my 58 soon. I don't know how to post a link to the photo's but I could e-mail them to someone that can put them on a link. They are beautiful.
