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

Why not ?
Studs and flange head nuts work just fine on other motors, I don't see why it won't work for this application...
I always liked it because it made lining up a tranny easier

Yup- goes on straight.
Just have to remember- don’t tighten a nut as tight as you do a bolt. Suppose that coamp force torque chart thing I did for the main studs would tell a person exactly how much to use.
I used stud on 2 just for alignment, never tried all of them. Hmm…
Taking the pic of the parts numbered section from manual and imposed the bolt size on it might make it easier if sticking with bolts.

Isn't that what the dowels are for?
I thought you meant the bolts with studs, but you mean thread studs into the block, then put nuts on the transmission side. That wasn't what I had pictured at first.

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.

Makes sense.

I also have some similar studs that are M10-1.5 on both ends.
I don't know where those go on the engines.
They're 30mm on the long side

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.

I have quite a selection of bolts with sawed off heads and screw driver slot carved in one end, just for alignment studs.
Been making them for a lot of years for all different kinds of applications.

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.
As long as it screws in deeper than the diameter of the bolt your good...

What's the part number for #11?
Do you have the part number for the similar 35mm long bolt?
Where can I find schematics like that?

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

I had 1 bolt that also measured 34mm
I'm just trying to find the part number that goes with them or the part number for TG he application or to verify that's the part number for the application. Because the dimensions don't match the hardware I have.
I looked for a schematic today, but never found one.
I used to be able to find schematics online.
GM should take a lesson from.Toro and post schematics and manuals on a parts Page

It will have to be another use other than bell housing. That's what most of the others have been when I've found them. GM needs a "where used" for part descriptions.
