Replacing the seal in the cable connection may do nothing if the cable is not attached. ORD sells caps. I purchased one as I no longer need the cable speedometer wih my LS swap. Cannot remember which one I purchased for my 72?

Maybe I can check my past purchases?
Sorry. past purchases are gone on my account, maybe call ORD and see which one they recommend?
