Michael,

The top right and the bottom left bolts are special BSF "Dowel Bolts" while
the rest are 3/8" Whitworth [BSF] hex bolts of varying lengths.

I just happen to have a completely restored BN2 bell housing for sale
currently on eBay...

You should get a lot of information from my pictures, then ask questions.

I got dowel bolts from BCS (they weren't cheap). Some say you don't need 
them, but I work on the 'If the beancounters at BMC allowed them ..." 
principle. I helped a friend convert his early Camaro to manual; the 
instructions from the transmission company were quite specific about 
alignment of the bell housing to the engine.

Michael,

*<Looking at your auction picture of the throw out bearing carrier and all
the fasteners I am now more confused than ever.>    *
First, open up a Moss catalog and look at the diagram for "Clutch 100-4".
This will answer a few of your questions.

*Restorers Tip: The Moss catalog with its excellent exploded diagrams are
an invaluable resource.*

*<The top two pins with the threaded ends are for the carrier, no?>*
Yes, these are Moss part nos. 53, 54 & 55 and the ones I have are
originals, i.e., they have 1/4" Whitworth [BSF] threads. The replacements
that Moss sells have 1/4" UNF threads. They work fine, but you'll need to
buy them as a set.

*<Also, where do the four bronze bushing go?>*
Back to the Moss catalog diagram, these are the four [4, no. 46] bushings
for no. 42, the steel "SHAFT, clutch operating". I assumed this was
obvious. These will need to be pressed into place by a competent
mechanic or machine shop. The same with the first motion shaft "Oil Seal".

*<The two bolts on the left side of the lineup of fasteners are the dowel
bolts?>*
Yes, but these are two modern UNF ones that I had modified. The shaft of
the bolt was slightly too large, so I had to machine them to size
to precisely fit the holes in the bell housing. They're not exactly like
the originals but close enough. Besides, no one is beating down my door to
buy this bell housing.

*<Are there supposed to be two short bolts to go on the bottom so as to not
interfere with the oil pan?*
No, please read what I wrote... <The *top right* and the *bottom left bolts
are special BSF "Dowel Bolts"* while the rest are 3/8" Whitworth [BSF] hex
bolts of varying lengths.>

See the photos I sent of the lip of the case. If you look closely at the
top right/bottom left holes, you'll see a circular machined depression for
the dowel bolt heads.

Below are photos of original dowel bolts...
The dowel bolts in my car were machined by Roger Moment off of two
originals that I had.
FYI, the remaining seven [7] BSF standard hex bolts secure the gearbox to
the engine, however two [2] of these bolts are slightly longer [1/4" to
3/8"] to secure the starter.

This should give you everything you'll need to know.

Curt

Here are the Dowel Bolts properly attached. As you can see, the bolts are
"just" long enough to fit with a period correct thick spring washer.

Top right...

Bottom left...
