Did mine recently, an absolute c*nt of a job, same as you, seized on.
I used my plumbers torch with the regular gas, which is rated at 'pants' for this kind of job, you may wish to try MAP gas, which I believe is much hotter burning.
10 minutes of heating is mind numbing to undertake, but necessary because everything is a cold sink.
It will release eventually, and I too had to hit the beejesus out of the yoke as well as using the bolt as a press.
Wire brush the splines and apply plenty copperslip on it when you refit, and it's important to renew the locking tab washer, I got a kit of 2 new bolts, 2 new horseshoe spacers and 2 new tab washers for £14 on ebay,
Stealer wanted £20 for 1 bolt and 1 washer.
