Thanks for all the info everyone!  
The thing is, I have got in contact with a guy with a
complete 72 fasty for sale. I want to use this as a
parts car for the 66 fasty/red interior resto. I was
then thinking, that as this will be a full resto I
could as well convert it to IRS.

What about the front beam, are there any gains in
converting this as well? I know the beam of the 66 is
rusty, so likely it will be replaced anyway.

I am also thinking of the engine mounts of the later
cars, from the shoptalk forum and various other
sources, I have read that it is a definitive + to have
theese when converting to T4 power. But is it possible
to remove the pressed steel body-mounts from a late
style and weld them in place on an early car? This
would look clean I think, a lot better than having to
fabricate a custom body-mount that screams modified at
you at least.
