F2A Truck Centers

[railbass@a...]

I think I put this on the list some time ago but have not found an answer 
yet. I am modeling Q diesels and will be making a model of the F2A to go with 
an FTA/B set. I am using a Highliner A kit to build the body, but the 
question I have is whether the F2 had the 27'3" between truck centers of the 
FT or the 30' of the F3s and later F units. Except for the small 
numberboards, they looked like an F3.
