Default cant get rear end of driveshaft off

Nothings easy..lol
Replacing the driveshaft today. Got all the T40 torx bolts out. Got the center support down. Got the front end of the driveshaft off....now the rear end off the driveshaft won't budge. I have used PB Blaster on it. The only heat I have access to is a blowtorch... ihave not tried that yet.
Can anyone suggest a trick to "unweld" these parts?
Thanks

I imagine I could reconnect the front flange and the center support, but not reconnect the rear flange. Start the car, put it in reverse and this might twist the rear flange loose. Could doing this damage anything?

Fixed...PB,d it overnight. Then attacked the 2 mating surfaces with a wire brush attachment in a drill. PB,d it again, then tapped the cv joint with a hammer and it popped off.
However.....the new shaft did not have the bearings in the front cv joint. Transferring the bearings from the old shaft was no fun...I took it to a local mechanic where the 2 of us spent an hour trying to get them in. We figured it out but it took both uf us to figure it out..lol.
The driveshaft center support on my d/s did turn out to be totally shot. The rubber was torn all the way around and the entire shaft was able to move a great deal in any direction.
Now putting the shaft back on SHOULD be a walk in the park after all this!!!!

Well done!
You were probably to cautious a judicious skelp with a hammer would have done the job.

I was pounding pretty good the 1st time..lol.
Just finished getting the replacement shaft on, went on without issue. I "neverseized" the bolt threads.
I better go for a test run :+)

Test run not good....lot of vibration...more than with my totally cooked old driveshaft.
Think I may have to buy a brand new unit
