Technical '37 Chevy Frame Measurement

Attached is a diagram of a '49-'54 Chevy frame and it shows the measurement between the outside of the front frame rails as 26 and 31/64". Could anyone tell me this measurement on a '37-'39 Chevy frame? I've been searching and I can't find that. That's to the outside of the box section of the two frame rails--not the bottom flange. Thanks, Bruce in Florida

 

Let me know if this is of no use and I will measure mine.

 

I think 1939 Chevy frames are totally different then 1937-38. 37-38 had either knee action front end on the masters and straight axle on the standard.

 

Just measured 3 I could get at -
37 (maybe 38), looks like it may have been beam axle 27 9/16
37 (all stock, knee action) 27 11/16
39 (master deluxe coil spring car) 27 3/8

 

You may find something in this if you haven't look already.
