Well I'm not certain either, LOL, and as old as these old girls are, there's every possibility that the steering box is off of a later/ earlier model, too.
I've been told that IDing the late/ early manual boxes is easy
I dont see the difference! They are both shiny!! :sign5:... Im actually going to run out the the garage right now and look! Thanks for that pic! I saved it to my files for future reference.
