Does anyone have a pic or can explain where the speedometer cable is routed through after it leaves the firewall and before it reaches the tail end of the transmission. This was a conversion from a C4 to a toploader. The catalogs claim the 1966 automatic and standard trans use the same speedometer cable. I do have longtube headers, so some modification might be needed?
