Yes jethro it has both
I want to run the mechanical drive to keep it simple
I will post photos tomorrow of the modified drive to move the 90 deg cable drive up closer to the box

Jethro:
Looking good Rob

Speedo drive problems solved
Original speedo drive as supplied
To get this to fit I have to Cut 16mm of the end of the mounting pad.
TO use a cable straight on the speedo drive would run the cable straight at the exhaust
I modified the drive as shown to get more clearance
Speedo drive 15mm shortened to move angle drive up closer to gear box for clearance to exhaust
Modified drive fitted to gead box

Trail fit magnum to 76 auto body
Trans in position
I had to cut the tunnel to get the box up to the correct center line
the section removed is the area where the original auto shifter was mounted .
this section protrudes down towards the gear box about 32mm.
the hole will serve as the shifter position.
in the photo above you can see the trans mount the bottom of the mount is 10mm below a lone taken across the bottom of the chassis.
this photo show gear box sitting at center line of original box
there is just adequate clearance.
note the top of the shifter area is at an angle that is standard in the design of the gear box its about 17 degs to the left side.
this is a 76 auto body I would think there will be less room in a 70 model manual body I will know in a few months if that is true.
the photos could be better but that is how it is when you take them with a phone in the middle of the night

modifying the transmission mount
the tremec magnum rear mount is 3.1" to the center line of the out put shaft
I have machined this to 2.785"
the Mounting pad is now 5/8" think at the mounting bolt hole
I removed 0.225" ( 5.715 mm )
the mounting pad on box comes set up for chev and ford
I machine the the excess off
