The cable on my 69 442 broke. The one from the floor shifter to the transmition. I'm having trouble finding a replacement. Would anyone have an idea where I could find one. Thanks

 

Here is an NOS cable, they are also reproduced and sold by the usual suppliers, Fusick, parts Place etc.

Same cable used on many GM floor shift cars. So look at Buick and Pontiac even the F bodies used the same cable.
While you are in there lube the shifter and the back drive linkage in the column and under the car.

 

And make sure the grounds straps are intact between body and motor.

 

I have one on order. Thanks for the help.
