The TR2 had it driven from the tranny, I assume the Devin would too.

Should work fine, however the calibration will be for original size tires &
diff.  All TR2-4 (and on partially into TR6) used the same speedo gears in the
tranny (speedo cable turns at 2/5 driveshaft speed); the calibration for diff &
tires was done at the speedo head.  If yours doesn't match, you can have a
speedo shop make up a ratio adapter for you.  The calibration number for the
speedo head is printed on the face, and is turns per mile at the speedo cable.

Cables are available new from the likes of TRF, Moss, et al.  The standard TR2-4
cable is 69" long, the overdrive cable is 96".  The TR6 cable also has the right
ends, and as I recall is in-between these two lengths.  They're only $15-20
each, hardly worth fooling with a used one IMO.
