Pictures!
First I replaced the water pump. I also deleted the vacuum line that crosses under the timing cover, because I figure having the vacuum line exit on the left from the pump, then go to the reservoir, and then the vacuum booster (all on the left side of the truck) is simpler, and avoids routing things near that exhaust.
I also did the Timing Belt. That's a new belt, pulley, and tensioner. Plus, the camshaft seal and the oil seal around the IP shaft were replaced with new.
Once that was buttoned up (although not for the last time, but for now....) I bolted on the AC bracketry....
And then I set to tinkering with the exhaust.
I must say that putting 308 wire in the MiG sure works a treat! It really welds very nicely on the 304 stainless. Much easier than I was expecting. I will say that the tack welds are MUCH stronger and harder to undo than my tacks in mild steel. Part of my tinkering involved removing some of the stuff I had tacked, and I must say it was a LOT more work that cutting the tacks off of mild steel.
Here's the (mostly) finished product.... You guys are right, it will be plenty easy to fabricate a new brake line from the master cylinder all the way to the rear axle along the left side of the frame, and I can fabricate a heat shield over the small section on the right rear where the brake line will be somewhat near the exhaust. Easy enough.
Here's a mockup of the bracket to hold the exhaust. I bought 304 stainless flat bar for this. The factory Toyota rubber bricks will attach to the exhaust, and I will fabricate a mild steel bracket to hang it off of.
This exhaust alignment keeps the exhaust entirely above the frame rail, and should have plenty of clearance around the driveshaft. The only thing I haven't decided is what to do about a muffler, if anything. I have enough tube to weld up a straight pipe, with a removable section that could be replaced with a muffler. I don't think I need (or want) much muffling at all. I'm seriously considering just putting one of these on:

But I'm also considering a more traditional (but still pretty compact) muffler like this:

But then, maybe just a resonator would do well?

I'm pretty sure the turbo will do the VAST majority of the exhaust muffling, but I don't want to hear a drone on the highway. I got one with the faux-lux when I ran it with a straight pipe for a while and I loved everything about the exhaust, except for that drone at 43mph going up a very specific hill. Of course, I drove that hill enough to realize that it only happened at that speed (the speed that the truck went up the hill), and it was positively maddening. So I put a muffler on it. It's that drone that I want to avoid on this truck too.
EDIT--another option is for me to just attach a turndown at the end of the exhaust at it sits now, and evaluate it once I drive it. Decide how much of a muffler I want on there after putting some miles on it. It would be VERY easy to add a turndown to the exhaust where it is now.
