Looking good! I chose a Clairmont for my first build, as well! Kind of wish I held out and found a vintage bike to clean up. Current production Schwinn's just don't live up to the name.
Good thing you can weld! You'll need if if you want to use your chain tensioner. After a near-wreck caused by my chain tensioner exploding my chain, I managed to do without out of shear luck. But you're better off with it, and welding it to the frame.
Also, that tensioner's mounting bracket needs to be bent to line the wheel up with the chain. It's hard to explain, but you'll see when you get there.
Only other problem I really has was the lower engine mount, but it looks like you managed that (hopefully without drilling).
I bought my kit on eBay from luckyearlybird. If you got the same kit, heads up: The throttle is wonky. Once assembled, there's almost zero travel in the throttle grip. It needs to be disassembled and a small shelf filed down to allow the throttle to back off. Otherwise, she's basically running on full all the time.
For a lead on a speedometer, the local Walmart has some Schwinn bicycle computers in their clearance aisle.
Also, as much as I like the look of the leather bags, they look heavy. You're probably going to end up removing them. Weight seems to be a bit of an issue. I had some old cloth saddlebags I wanted to use, but I'd have to shorten them (they aren't motorcycle saddlebags, they're ACTUAL saddle bags from the Indian Army or something! lol). I opted for a plastic milk crate mounted to the rear cargo frame. Not perfect, but easy!
Good luck!
