727 Identification help please

I picked up a working 727 for dirt cheap but I don't know what it fits. Floundered around for a while with the part number decoders but i don't see this one listed. Can anyone tell me what this came out of?

PK 4329438 8099 0576
It has an A-727 cast into it which leads me to believe it is for an A body.
The tailshaft has the number 83 1 051111 4028194

Thanks, Gary
