A999 as a street/strip trans.

So, the guy I have been chasing for a month that "thinks" he has an A999 out of an '86 van finally gets back to me with a PK number.
4412465.
I cannot find that number ANYWHERE!!
the only numbers I can find with 441 are "industrial/marine" transmissions!!!
And they look to be 727's...
The only list of numbers I have is the one in the SA design TorqueFlite book.
Anyone in here recognize this number?
Or am I doomed to drive an hour to find out its not what i want?
