Mark,

The exercise that you are entertaining might be better for the 87100
series. Bear in mind that the P2K car is not really suited for either series depending upon the final result that you are after.

87000-87024
10-4 IH, D-4/5 inverted, Creco doors, double rivet-row, end-door.

87026-87099
10-4 IH, D-4/5 inverted, Creco doors, double rivet-row.

87100-871099
10-6 IH, D-5/5, YSD-4/5/5/4 doors, double rivet-row.

The lower end corners do not match the P2K and neither of the
NKP series featured the push-pockets as exists on the P2K cars.
Also, the P2K cars are inteded to be a 10-6 IH design.

Again, it comes down to the accuracy that is acceptable to you.
