Bellhousing identification

[Pale Rider]

I could use some info of you gurus out there.
I need to replace my bellhousing and need to know what I got and thus what I need.
I don't have the tools/skills/space to disassemble the tranny to see the casting nr. If I let the repair shop do it, it will cost me appr. 250 Euro...
So I tried to do it based on pictures and I'm pretty confident that it is a big block 11" bellhousing for a '69 B body, nr 2892626.
Some additional info about my 4 speed: PP833 2415 0201 which means an A833 4 speed manual built on March 8th 1968, nr 201 on that day.
This is my block when it was outside my car a couple of years ago during the big restoration:


And this is a picture I found on the Brewer's Performance site:


In my opinion a perfect match.
So I could go for this reconditioned one.
But I saw this one (Keisler Big Block Bellhousing (A833 18-spline)) on the Keisler site:


New, aluminium (lighter) and cheaper ($300 in stead of $400 for the reconditioned one)

What I would like to know is, if I'm right with my identification and if the Keisler one is a good option.
Perhaps the first question can be answered by AMXguy; in this topic he mentions that he has this 2892626 bellhousing in 2 of his cars.

a 1970 big block e body bellhousing number is a  513  last 3 digits.  383 440 426  my 70 440-6 cuda is a 513

To be clear; the previous owner converted it from an automatic to a manual and he obviously didn't use original E body stuff.
I know what kind of bellhousing they used for E body's. But I want to know what is in mine.

Well, cast iron bb bell is 11 inch flywheel 1969 and aluminum is 10.95/10.50 1970 scallop. Yours looks to be cast iron. I dont see the boss on the side for the 70 key removal/reverse park.  A 10.5/10.95 is a 132 tooth flywheel to.  Pulling 4 bolts isnt difficult where your picture is taken. Then you can see if it's an 18 spline or 23 spline. Take ou 10 minues and a 5/8ths wrench

This picture is from a couple of years ago. The engine is in my car.
I did the magnet test and it is a cast iron one.

most cast iron belhousings have the 143 tooth 11" flywheel , you can mark 1 tooth & count your way around the flywheel to be sure

Another thing - that trans is an A-body version.

Roland that does lok like a 2626, but there may be others that look about the same I can't say.  you could count the teeth on the flywheel to see if it's an 11" or measure the outside holes on the dust cover, the 11" one is wider.

[Pale Rider]

I will remove the dustcover and count the teeth, that is doable.
Keep you guys informed.

[AMXguy]

If you want to measure your dust cover hole width I can check mine for comparison it will give you the same answer, as I recall the 11" is about  1/2" wider. they won't interchange I'm sure of that.

OK, took a dive underneath my jacked up car. Ain't fun when you're 6'9"
The plastic cover has been modified at one site so measuring that was no option.
Instead I measured (as far as possible) distances between the 5 bolts with which the cover is fastened.
If I would number them 1 to 5, I was able to measure the distance between 2 and 4: appr 11", and between 1 and 3 (same as 5 and 3, 3 is the center bolt): appr 9".

I was also able to see 3 bolts on the flywheel. I've counted the teeth between 2 bolts and that was appr 25. With a standard 6 bolt pattern this would mean 6 x 25 = 150 teeth. With the inaccuracy of this counting method, this would point to a 143 teeth 11" flywheel.

Just took a picture of the bearing retainer hole (whatever it is called). You see parts of my Keisler hydraulic clutch:
