You know what would be really nice? Having the Sacramento fab shop cut out a new skid plate from their old CAD files (no bending, welding, or paint). Then I'd have a perfect surface to fabricate my ribs, etc. I've sent them an RFQ.

Of course, should I go down that route, maybe I should have the skid plate cut from better steel. What alloys are available with a 50+ ksi yield point, as delivered? Easy mig welding is a must, with no pre- or post-weld heating (or at least very simple procedures). I'm not interested in getting the finished skid plate heat treated. Must be available in 3/16" thickness or very close to it. Maybe A588, 4130, A572, or A514?

3/16" A514 T1 plate would be amazing. Will welding it be straightforward for me, a relatively unskilled hobbyist?

What about 4130?

 Check out KVA's MS3. They're in SoCal.

Between the eternally leaking A/C and this stripped thread, it's as if real auto repair is intruding into my fabrication / electronics thread!

Is it leaking from the old fitting that's meant to be welded shut? If so you might do some brass or silver brazing where it's a little easier to add lots of filler material in an air tight way than with a welder. You could also use a swagelok fitting with a plug there.

I liked this idea, but a rebuilt kit + torque converter is actually quite expensive.

$??? junkyard, pick it myself
$600 junkyard transmission, shipped
$700 rebuild kit + torque converter
$2,400 rebuilt transmission from dealer
$5,000 AWD 2nd gen Sienna in much better condition
$10,000 Old 4WD 4runner with high miles

There's a guy on craigslist parting out a 2000 Sienna. That's probably a good place to get a transmission, side window glass, and other misc poo poo all at once.

There's sure to be at least one Toyota recycler out on Recycle Road in Rancho Cordova sitting on a pile of these transmissions for cheap.
