Steering box Id?

[Jim Haskins]

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.

Thanks Jseery. It looks like I have a 40 box. Now I must figure a
way to mount the 36 liights. Jim Haskins

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

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.
