MAF question.. need part number for Series 2

[FriedEGs]

I am in need of a maf for my series 1 RB25DET. I found a maf for my motor, but the number doesn't match mine. I'm trying to figure out if this MAF I found is for a series 2.

2 questions:

1) Can anyone supply the complete part number from a Series 2 MAF? (excluding the first 5 digits.) should say, 22680 xxUxx G or J 60 or 70.

2) Are there any differences, or usability issues if I used an S2 MAF with an S1 motor?

Thanks for any info!!
