Can someone help identify this box. Casting numbers
found appear to be 91a-3550. there is also a circled B and the number 10 on it. It was purchased as a 37 box, but does not look like one I have seen. There is no light or horn box switch accommodation on the bottom .a small hole only.
Thanks for your help. sorry cannot seem to load pictures
 
Sent you a PM.

This is not going to be much help! Per the Green Book the assy numbers should be:

78 3504 37
81A 3504 38-39
01A 3504 40-41
21A 3504 41-47

The housing itself should be 3548. There is not a listing for 3550, it jumps to 355X which start the bearing and race numbering. There are no 91A prefixes on any of the parts.

Is it possible that it's missing part#3569 like in this diagram that the light switch goes in to?

I think you should still be able to fish the horn rod through the cover ? Then you need the 2 bolt clip that attaches the switch
 
Thanks Jseery. It looks like I have a 40 box. Now I must figure a
way to mount the 36 liights. Jim Haskins

You will need to replace the steering shaft with an earlier version that has a center hole large enough for the '36 light switch/horn rod. If your worm gear is good, it could be pressed off the '40 shaft and back on to an earlier shaft with a larger hole. There are some recent threads here explaining how this is done with pictures. It is not a difficult thing to do but you must have the correct size press and the fixtures necessary to do the job correctly.
