64.5 Clutch Release Equalizer
« on: July 25, 2019, 08:48:24 PM »
Does anyone know how to tell the difference between a 64.5 and a 65/66 clutch Z bar?

Early Mustangs had a clutch adjustment at the top of the bar (to 6-20-64 ?), later Z-bars had the adjustment at the pressure plate arm. I'm not sure about the adjustment changes. A different bar was used in 66. On February 14, 66, an additional spring was used at the top of the bar to the firewall. That makes four bars for standard 260/289 engines, and four for HP engines.

The lower arm welded on the cross shaft tube was a bit shorter and straighter, and the cross shaft tube was a bit longer.

My picture shows reproductions, but they were right on the money. Note: The repro early non-hipo bar is no longer available.

Thanks Brant. That was exactly what I needed to know.
