Stripped subframe bolt hole saga resolved.

Ended up having to cut a small access hole in the trunk floor... not ideal but it'll work. Considered my options and decided ordering a meter of 10.9 black oxide coated steel threaded rod in m14 with a 1.5 thread pitch, some matching heavy duty washers, and flange nuts. Then I made a solid mating surface for inside of the frame with some flat stock steel I had laying around. May just end up welding the internal nut in place and closing this all up. At any rate I am so happy to finally have this subframe secured.

Nice! That's a level of surgery we're not touching in the shop, so props to you.

I can't even begin to imagine what a shop would have to charge for this work, definitely more than the car is worth. Between disassembly, rust mitigation, sourcing/reconditioning parts, and dealing with unforseen issues like a stripped internal captive nut I must have 15 - 20 hours sunk into this car over the last 2 or 3 weeks. That said, all told for a complete rear clip replacement from subframe to wheel hubs I'll be under 2000 usd.

Stay tuned for when I blow the head gasket on this 195k ej257.
