Trust me, I don’t want any more issues or screw ups. It’s a 17 mm bolt, I will try the thread chaser 1st. I am thinking of taking off the left side bolt (already removed, torqued to spec per the FSM) to use for measuring and comparison. If the thread chaser doesnt work, then I will go to the tap/drill bit. If the bolt is 17mm, should I use a tap for 17mm or should I just go up a size? Yes, I need to know thread pitch. On a bright note, at least it’s cleaned out and the problem is easily accessed. This would be 10x worse if it were up inside and more confined.

If you tap that hole to 17mm you are in for a surprise. That's a 12x1.25 bolt.
 
When chasing use oil and go a half or full turn then back clean the material out as you go. A compressor with air helps blow the bits out. Nice work on not giving up!
Will do, yes, heading out shortly to find the thread chaser/tap and drill bit. I was almost at my “absolute Witt’s end” 😆😁
 
Thank you, the bolt head is 17mm, I will find use the correct size. The left side bolt will be my guide. This has been quite a learning experience.
Yes it has. But it will be a great feeling once you have it fixed the right way.

You'll probably never have any further issues with it, but when you re-assemble, you could use some anti-seize.
 
Yes, that’s the plan right now. I am hoping for no more issues, the rear suspension bushing replace project would have been done a couple of days ago. BTW, this broken bolt fiasco will put me on a campaign to slowly replace all suspect looking bolts. Lol. 😁
I just had a mini Ah-Ha moment. Since you have an import and from some of the photos you posted, the underside looks decently clean and rust free. I wonder if whoever last touched the bolts used loctite's red permanent grade. Only way you were going to have a shot at removing before you snapped off the head was a fair amount of heat beforehand.
 
Getting this pig ready to go back in!

A local Toyota dealership (GASP!!!) installed the suspension. If they did use red Loctite, why was the left side bolt effortless to unscrew? Thank you for the thought though, I will be approaching ALL suspect bolts with heat in mind. The dealership may have also overtorqued the bolt with an air impact.
 
Part of the park-lock release.
 
Well I tried to plug in a fuel pressure test kit into the rear end of the fuel rail to diagnose a P0171 under load issue, and this banjo bolt snapped off. Now I'm thinking of whether I would be able to remove the stuck piece out of the hole or do I have to stop procrastinating and remove the air intake chamber and reseal the fuel injectors while I'm there?

Got the motor mounted to the Tranny, starter installed and made some custom plates! Still have to swap the gear onto the new power steering pump and a couple odds and ends hopefully be up and doing some break in on the new motor in a couple weeks.

All,
the thread chaser worked really well. Not perfect but it will do. Made some turns in, backed it out, made some turns in, backed it out. Whenever I felt resistance, I backed off. I used plenty of oil and took my time. My test (and temporary) bolt fit and locked up tight. There is some damage to the threads towards the front but the damage doesn’t extend very far inwards. Even the left side bolt used for measurements and testing as well, locked up tight. Final picture is the shock mounted and the bolt torqued to 51 ft/lbs per the FSM.
A big thank you to those whom have been following and provided advise and help. This is great community and you are what make it even better.
All that’s left to do is torque up the rest of the rear suspension bolts and nuts per the FSM to be complete tomorrow. There is also a fuel filter change that I want to do tomorrow as well. It is still weekend after all. Happy New Year!
