All this bolt confusion is why I like to use studs for the bellhousing...

This is what was in it when I received the engine and transmission originally. I have all those bolts and in fact 3 of them are holding things in temporarily until I get the stud situation worked out.In my H1 99' with 4L80E

I have quite a selection of bolts with sawed off heads and screw driver slot carved in one end, just for alignment studs.Doing a lot of assembly with heavy components- most guys buy some all thread aka threaded rod of all different sizes/threads. Cut them into 5” or so lengths and clean the ends of threads up. Then use a thin wheel and cut a screwdriver slot in one end.
Then keep a nut with each one. Very useful extra in the tool box.
If the proper 34mm length was unavailable, would it be recommended to buy the 40mm and cut to fit or buy 30mm length? 40mm is too long for the application.
What's the part number for #11?Yes, #11 is correct for what I'm referencing. Same fastener is used on a manual transmission truck on one of the top passenger side bellhousing studs for securing the clutch line. The double ended stud also had a grounding strap on it from the starter on my '95
I'd like to see the part number in a schematic. The studs I had here all measured 34mm@jrsavoie the link posted earlier by Ryan is probably the correct part
