1970 4 speed reverse lock out linkage

I've only seen one and that was 35 years ago when I took mine off My 70 340 Swinger and tossed it. How many of You did that? I bought this set up from Tony's auto parts and paid up the *** for it. I told him it was for My 70 340 Swinger so I assumed I was getting the correct parts. I've bought many parts from him and never had any issues. I'll contact Him and hopefully He'll take care of this for Me.
