Interesting...The case itself is a 1991 model year case, WAM indicates model however I don't know what specific model...

What are you trying to install this 700R4 into? A Corvette or a Squarebody truck?

Here's a break out of the casting numbers and their respective meanings:

A "K" case has a thicker flange that the dust shield bolts on to. I think That k case was a
HD truck trans. Good starter trans for a beefy build.
