Driver size of the Bachmann AT&SF 4-8-4

[ryeguyisme]

Does anyone know if the driver size in N scale is 73 inches or 80 inches?

I need to know for a project I'm working on that I will feature here eventually!

Thanks

Bachmann tolerances are a sloppy +/- .010 in "N".

With calipers I measure .464 over the face,
and;
.520 over the flanges.

My math says .464 X 160 = 74.24 in.

YMMV

Thanks! Just ordered a new one. I will be making a D&RGW M-68 class 4-8-4 soon. Will be posting on here the results.
