OK! I got the new tank. You tell me "which is sexier"?. I did have to chop the old front mounts off the neck, and re-position them back and up a bit, so swapping tanks in the future is out. And I had to build a under the tank rear mount.....which I have fabed up, but haven't welded yet.
I was excited to post the difference, wadda-u-tank?
Back to the seat pan for a while. I bought a metal spun bowl from Wall mart for cheep. I was hoping to get the shape that was needed. I ended up whittling it up quite a bit, till it fit..... then I had to add some length with a piece of sheet metal I had laying around for just such an occasion. I am running low of inert gas for the welder, I am broke....so i am just tacking everything together and will spend some time finish welding later once I get a new bottle of gas.
Now I just gotta freekin match this up. Not as easy as it sounds really. But the good news I didn't have to do much drilling. the left side was a tool box opening side cover. All i had to do to get the cover off was to wack the hinge off, and chop-er in half to start. Then with some snips and a few pounds with the pound'in iron we were starting to see a shape that was familiar.
Got the top shape somewhat there, now as with the right side, we need to make proper gap. A slice and a dice........some welding.
and there we go..side covers!, and now to boxes and mounts. 
On a sad note we opened the clutch cover 'just pokin around"and found a nasty little surprise. A broken clutch basket tang. Never seen this before on any bike, and I'm really glad it didn't get into a gear and trash anything else. Tis a-bummer though, and it will have to be dealt with. Now I just gotta find one????
