Just bought my 1st Jeep [M38] and I'm trying to fix the horn. It is/was a dash push button but I want it back in the steering wheel. I removed the switch for multiple reasons. There was no hole for the rod [missing] but rather a seal of some sort and when I poked a 1/8" rod thru I got a bath of GO. The box has been rebuilt and all is tight in the front. How do I get the adapter out because I believe there is no tube thru the box? I don't want to undo the work that was done. Can I remove the side cover and drift it out after removing the box? TM 9-1804B did not address the adapter.
Actually it appears none of the manuals offer any real help. There is a rather large choice of manuals by the way:
Ross Steering Gear Civvy Manual (in my photo album) No Help!
TM9-8615 Ross Strg Gear Military Manual No Help!
TM 9-1804B M38 Running gear (only mentions the adapter once in Insp)
SM1005 & SM1046 Willys factory manuals for CJ's do not use a bottom mount horn switch. No Help!
Oddly the M38A1 uses a different adapter RG PN 402141, WO# 806915 which TM 9-8015-2 M38A1 Running gear says is threaded. The comparison of part numbers between the M38A1 & the M38 will further skew the whole program.
M38 Parts List:
Adapter, Horn switch -- ORD# 7375150 WO# 801717 RG# 402130
Switch, Horn ----------- ORD# 7375088 WO# 800299 SRM# E8240A
Tube, oil seal ----------- ORD# 7375337 WO# 801186
Tube, oil seal w/adapter ORD# 7375342 WO# 801716 (this includes both Tube 7375337 & adapter 7375150)
You can interchange the adapters. Yes, Wes is correct in that there were 2 different part numbers, but you can use the later designed adapter in either gear box. We manufacture the later type adapter and have them in stock.

Thank you all for the information. I'm going to try a pipe wrench to see if I can twist the adapter loose, if not then I'll be digging a hole to remove the assembly. And based on the picture from Wes I'll have to disassemble the box to get to the adapter if I need to drift it out from inside the box. Again, thank you all for the quick responses.
Not as of yet. I just pulled the rubber button off and tried to get a 48" x 1/8" rod down the shaft trying to find the tube using a piece of leather cut into a 5/8" circle as a centering guide. I know the rod is missing and most likely the mid tube spacer once I see a picture of what that is. I will look at/download the Ross Manuals. I've downloaded most of the TMs.
