Barrel Exchange, 1720T for 1701P

[MoonBat38]

 
I just received a 1720T barrel (Mike at TKO).  I want to install it on my 1701P.  Could anyone give me the basic steps ?
The new barrel will allow me to add a TKO extension.  It would be very helpful if someone could steer me to a picture of a disassembled 1720 shroud.
Thanks,

Art,
Thanks much for the exploded diagram (and parts list).
With the picture, it was a fairly simple job to exchange the 1720T for the 1701P barrel.
The new barrel, shroud and TKO extension are now installed.  I plan to try it tomorrow in my (sadly abbreviated) garage range.
