4x4 Propshaft help needed

Gentlemen,
I have an early 4x4 two piece propshaft. The hexagonal thick donut type.
It is seized at the splines. I think the splines are twisted as penetrine and a hammer will not budge it.
Could anyone provide the length of the male spline measured from the centre of the yolk or from the
forward face of the centre bearing to the end of the spline. This will allow me to determine where the
end of the spline is in the rear of the forward shaft. I can then cut the forward shaft and attempt to separate the two.
I could drill small holes in the forward shaft, however am hoping to fast track that one.
I don't wish to buy another shaft until I know what is going on with this one.
I cannot find a serviceable early thick donut anywhere. So am looking at a mod kit from the UK, which requires shortening the front shaft. I may need another 4x4 shaft(s), yet to be determined.
I have spoken to two driveline experts and they are 'wary' of the donut. I am not prepared to eliminate the donut as it is there for a reason.
In the meantime guys, any assistance will be appreciated.
For those wondering what this driveline is from,  it is the ex Mark Keen ex Kevin Hinchcliff 3 door with 4x4 running gear.
Regards,  Al

    Al, drill and tap a small hole well forward in the expected cavity in front of the spline and hook up a brake line from a master cylinder to it...you could just get a length of bundy tube and make a temporary line off the master cylinder in the car,bleed the air out then...1500-3000psi of achievable pressure should dislodge it!!

    Phil,
    Thanks for that. I'll try it with one of the runaround cars in case I blow the master cyl seals.
    Do not underestimate the power or hydraulics, I think you are saying.
