Would a 727 out of a 77 Van work in an A body?

Yes. Only diff might be if the A-body has a stock floor shifter. The van/truck trans usually don't have the mounting support on the lower side of the tailshaft for the stock type A-body floor shift linkage. Even then it can be used it a car style tailshaft is swapped onto it.

I have three of them in storage, one out of a truck and the other two out of vans and they have the two bolt mounting for the console bracket. I wonder what years they had a different tail shaft?

The better news is, they may actually be built a bit heavier duty than the car transmission. Like better/more clutches, or better bands.
The van/truck ID is there is a hole at the top of the bellhousing area, for timing. Ya can't get a light on the crank easily when it's in a van situation, thus the hole.
Good luck!

Not all of the truck/van tranny's had this, I think they started doing it in the 80's for only a couple years. My van had a bracket mounted to the timming cover for a timing probe.

The trucks and vans are a cheap source for tranny's, most people don't think to look at them.
