stock chip ID

[stickybones]

Sorting thru my collection of car junk and came across 2 old chips for my 87 GN. One is the stock chip and the other is an old Dynotech Stage 4 chip. Trying to figure out which on is which. I think I know, but I'd like to be sure.

The one I think is stock has a square silver label on the back. Can't read the whole label, but part of it has a line that reads BBKJ. Below it, I think it says 9460. It also says something above the BBKJ but I can't read it cause the the little plastic bar on the chip is blocking it...much like the other little bar is blocking the 9460????

Is this a stock chip?

Thanks

Yes BBKJ is the 87 recall chip.
