Are 2 & 4 Door Bench Seat Tracks The Same?

[Old Moparz]

I never got the seat tracks & the related hardware with the bench seat for my 1968 Coronet 500 convertible & need to find a complete set up to install the seat. I need both the left & right tracks, along with the adjusting lever & the cable, but I was wondering if these items are the same for the 2 door & 4 door cars. It would widen my search & I would assume they are the same, but does anyone know for sure? 

Thanks.
