If I raise the rear wheels off the ground in neutral and rotate one wheel the speedo cable should turn? Because it doesn't tried rotating the cable at speedo end and just winds up like a spring like its seized or connected to the gearbox drive.

No, the diff will just spin the opp wheel. The gear drive comes off the output of gearbox, so you will damage the cable if it’s connected at gearbox end and you just try to turn it at the speedometer connection. 
if you want to disconnect it at gearbox and speedometer it should turn with little resistance. You can also connect it up at speedometer end and carefully spin the gearbox drive end with a drill, that will then operate the speedometer.

Hi ya. 

What about  putting the  car on a decent  pair of stands on level  ground  and drive it as normal  to see if speedo is working. 

Did it in mine the other day  after  putting  gearbox  back in. 

Got up to  50mph going  through the  gears..😂

Good fun 👍
