If all else fails, then I would suggest you look into Holley Part #11-4 DASHPOT this is a universal model Holley now provides, there website provides a number of brackets to support this dashpot. Dashpots were standard on the 60"s era Holley four barrels on Shelby GT-350"s and while Holley site says for manual shift cars, Shelby had them on automatics as well. If you could find one of those, they are the best, vacuum operated. The dashpot when adjusted correctly cushions the closing of the throttle in the last 4-500 RPM to idle. They are designed to eliminate the problem of sudden throttle closure shutting the engine off.
