How long or wide is a 26-27 rear crossmember.
1926-27 frame rear cross member is approximately 42 1/2 inches from side to side – see: http://www.wescottsauto.com/Tech/FrameDiagram1926-27.pdf
From http://www.mtfca.com/discus/messages/179374/182334.html?1295043894 the below photos were supplied by some faithful forum member – I apologize I do not recall their name (if someone knows who was kind enough to post them originally – please drop me a note and I will add it to the file name for next time). The photo below shows the difference between the late 1913 to 1925 rear cross member and the “mid or so” 1926 to 27 rear cross member:
From that same thread thank you Jim Thode for posting the photo form his early 1926 rear cross member shown below. Note it does not have the flange that the later 1926-27 rear cross members have.
Good luck with your project.

Around 41" perhaps plus a fraction. I just took a quick measurement.
I like Hap's posting better
