My Car (Original 73, 4 speed) is over the Trans, and this is confirmed in
GM's 73 Assembly Manual. On Original 4 speed Cars there is a welded
on clip on the Drivers side Trans Tunnel, and a bolt on clip (retainer) on the
Trans Mount Bolt (passenger side) that allows the Speedo Cable Run over the
Trans then loop into the speedo Gear to avoid binding the Cable. The Welded
Clip on the Drivers side, if you look at it is to keep that Cable away from the
shift linkage. It may be gone, and even if so, a small square welded tang
should remain, and allow you to properly locate a new retaining clip.
I can't say this is correct for any other year, but I also can't imagine GM would
run any Cable across the bottom of the Car, for obvious reasons. Even Brake
and fuel lines that run across the Car are either protected by the Frame, or
shielding on the lines. Nothing that could be caught or pulled would be correct
in my mind. Now a 74 uses both the Muncie or an ST10 depending on the build
date, so this could easily have changed with the change to the ST10 in 74 but
I would bet it's the same for all 4 speeds with the speedo gear entry on the passenger
side.
