I’m well past that point already.
Good links.
I’ll be retrofitting bolts. The blocks are wide enough that the sill plate doesn’t cover it all, so I can get concrete in there from the garage side now that it’s dug up. I’ll probably stuff some newspaper in so I only have to pour a couple blocks deep. And use a right angle drill from the basement side to put the bolts in. Might try to sneak j-bolts in from the garage side from under the sill plate, otherwise I’ll have to use all-thread. Then some kind of ties for the joists to the sill plate.
