1988-92 Camaro & Firebird V8 Accelerator Cable for original LHS and many RHD conversions.
This is 29.1 inches long.. its the complete cable and casing.
Illustration is a generic picture only.. not exact
This may not always fit each RHD vehicle.. so it can be sent to you and returned subject to your not trialing it or wrecking the packaging and the freight is paid both ways.. Can't be much fairer then that.
Alternatively ..you may need to look at Commodore or other cable makers to make something for you is the RHD car cable is converter specific.
