If the S12 cable is long enough you only need to swap/modify the speedo drive mechanism in the gearbox.
Get a speedo cable from a Datsun 180B/200B/Bluebird (610/810/910).Also get the mechanical speedo drive from the gearbox. You might need to cut a slot in the speedo drive so you can fit it in with the correct gear mesh. This is assuming the Cressida speedo has the same mechanical connection as the Datsuns.
This is very common operation in Datsun transplant circles.
My old man runs a SR20det in his AE86 Sprinter, so it's got to be possible.
