Hi leadfoot,
First of, I love that rear fender.
Second, thats exactly what I wanted to do as well, ad a cowl but not cut of the subframe.
The cowl itself is an old XS650 tank of CL i got for $10. I cut it of, long enough to cover the sub frame fully. I got that idea from someone else in the forum, cant remember who, who did the same thing, but did cut of the sub frame.
I used 2 brackets from Ace Hardware to mount to the cowl and allow it to clamp to the point in the frame where the seat would bolt on, and drilled the tank (now a cowl) towards the rear to allow me to bolt it on to the part of the frame where the rear fender bolts were.
The best parts about this are:
A. It leaves a lot of space free in the back to move the battery which is next in line
B. The tab on the tank which used to bolt on to the fram makes a nifty mounting space for the tail light.
So its essentially a 2 part unit. The seat is separate from the cowl.
For the seat I used an old no parking sign (not saying where I got it) to make the seat pan. I bent it to form to allow it to bolt on the tank mounting bolt in front and rest against the sub frame in the back. I drilled holes in the center to bolt it to the frame at the brace with 2 holes by the battery box mounts.
I used a piece of pine to form the seat and fill the half circle in the cowl. I glued 2 layers of cut up walmart camping pads (thanks to some other guy in the forum) to them and streched some fake leatehr from micheals on to it.
I also used hardware brackets to bilt the wood together.
I finished the metal edges by using the trimming you can buy at a car parts shot for car door edges.
Here are some closer pics so you can see the process somewhat. I did not take too many pics during the process which I regret.
Good luck on the build.

Welcome from a fellow new guy.
I just got an 80 cb750 and am interested in what you did to make your seat cowl, I've been struggling with ideas to make one work without cutting off my subframe.
Here's where I'm at so far, seat fabrication is next on the list...
