WTB 1956 Cadillac Rochester Carb speed-up control for A/C option

[carguyblack]

My Carter carb was shot on my recently purchased car and I had a restored Rochester to replace it with. What that lacked was the speed-up control as this car has a/c. I had hoped the Carter speed-up would fit on the Rochester, but no luck.
Any help or leads would be appreciated.  Chuck D.

I have no idea about a part numer so the best I can do is show what it looks like on my Carter and another picture of the Rochester it needs to go on. Thanks for your reply! Chuck
