Are you sure it's a Muncie? The tail looks cast iron to me unless some of the older ones were... I do have a cast iron Warner here... If I were giving it my best visual, I would take it as a Saginaw because they had the 3 holes in the tail shaft for this counter damper... which I have never seen on a Muncie. (not that, that means anything... ) I will find a pic of one my Saginaws to compare.. YUP! All 3 do... Are all 3 shift levers in the cover? Looks like a Saggy to me.. For the record, I really like the Saginaws... shifting is really smooth in them... unless you are really bashing them... everything has its' breaking point!

Okay, I'm posting this but I'm really concerned I may end up looking very foolish.   I was taking pictures of the undercarriage of my 66 Acadian Canso yesterday and I wasn't able to get the car as high up in the air as I had hoped so some of the pictures were taken blindly by pointing the camera via my outstretched arm.

When reviewing the pictures later, I found a part behind the trans (muncie 4 spd) that I can't identify.  Check the picture and tell me what you see.

 I could only find reference to a Saginaw - Vega   4 speed   here is a picture (lower unit)   

Saginaw for sure. I pulled a 2.88 (if I remember right) ratio from a V8 Monza and it had that damper.

I saw a Camaro years ago with an interesting 3 link rear suspension traction system which bolted to the tailshaft.

That is so interesting.  I never ever heard of that part before.  Maybe I'm wrong but it seems like this car is from an area that people are not quite so quick to jump online and order up new parts from Jegs and Summit.  I will post a picture of the radiator in this car, another one I have never seen before.  Sorry the pictures aren't too clear but it appears to be a brass tank fabricated, one off unit???

A 67 Chevelle has a damper behind the Powerglide.  Supposedly the damper was omitted on the base 300 series but included on Malibu and SS396 series cars.
