Maybe I should crawl under my truck and check the bolts and bracket.

Starter bolt size
- Thread starter Stoney

My theory is that those heli coils rusted out and me having the starter in and out multiple times not knowing that those were what was in there, probably disintegrated them until the one fell apart and the bolt fell out.. put all the strain on the other bolt and disintegrated that helicoil

With GM you don't know, older block to bell housing bolts were 3/8's with 1/4" cap screws for the brackets.
Newer ones are Metric, with 1/4" cap screws for the brackets.

#6 bolt in denata's diagram is what moved on my starter and allowed the rear part of the starter to twist a tad bit after installing my missing bracket back when I first got the truck. I don't think the new power master starter have those bolts to be able to move like that. you might want to look at one as a replacement starter once your brother gets the bolt holes on the block reworked.

iirc it's an 8mm 1.25 unless the starter has been redone and the re-builders tapped it out to 1/4" 20 thread. use a grade 8 bolt. usually the starter has a stud where a nut goes on holding it to the bracket though.
got truck back yesterday... bracket was hanging from block.... so at least I didn't loose the bracket... Stopped at a.z . Got a new starter out of box to find size... That's when I noticed it's a stud... CRAP!!. .. bought bolts anything.. @dbrannon79 nailed it 1/4 -20....but not the damn srater has to come back out to drill out the rest of the stud.(assume there's some left in there.)

I asume the stud broke off from the starter? when you pull it back off take a good look at the face where the starter fits flush to the block on the main bolts. make sure the mating surface is nice n flat and mates flush with the block as not to have any ware spots that would cause the starter to "rock" uneven on the block. if it dose have an uneven surface caused by the loose bolts, then the starter needs to be replaced.

That stud is not standard. Some starter come in metric (m6 or m8) or SAE (1/4).
In my case, when I replaced my starter, the one in there and the new bought starter have different size.
I found it out by the need to use different socket.

also when you pull the starter, if your brother used locktite on the thread repair inserts. be very careful that they don't come out with the bolt not knowing if he used locktite on the bolt threads too.
