I believe the 63 4 speeds were the T-10 and 64 was the first 833...........................................MOPOST BY Anselmi: Would there be any demand for a 1963 Plymouth Max Wedge Borg Warner 3 speed? it has attached the Hurst 3 speed shifter less the handel-lever. I know for sure it is legit.
The 1963 Plymouth and Dodge Max Wedge cars (Manual trans) came with a 3-speed manual trans because the 4-speed could NOT handle the power/abuse.
The 1964 cars used the "New" Borg Warner T-10s
