Hi everyone. Hope someone can help with my horn button problem.
The hole in the steering wheel only accepts the older style 6 volt connector. That’s the spring looking one in the picture. The one on the right is what is called out for the 12 volt. Only problem is the hole in the steering wheel is too small.
I’m thinking of drilling it out to fit the new one but wanted to get some feedback from anyone who has had experience with it.
As always I appreciate all the help I’ve gotten so far.

That original contact shouldn't care about voltage. Try it and save some extra work. Fred
Agree.

Doug - I would also agree. If the existing contact has continuity between the brush end and the upper contact, it should be ready to do it's duty and no mods to the steering wheel needed. If there isn't continuity, lots of of NOS GM# 759037 horn contacts available on evilbay.

Doug, I purchased a 6v horn contact bushing (as it's described in the catalog) for my 1950 from NPD. It fit in the hole properly.

Don't forget to clean the contact points on the older set before you reassemble. Also the top edge of the steering column.

Doug, Does your pictured original contact set include a plastic sleeve??? According to the parts books, that earlier design original contact came with a separate plastic sleeve (like the bit surrounding the metal parts in the other contact you have), but it has a smaller diameter to the sleeve than that reproduction/replacement contact. GM# 759230 is the separate "plastic sleeve" for your old contact and should slide right into the existing steering wheel hole. I think that being absent is what's causing your horn to sound as the old contact isn't held in place correctly to prevent ground contact.

Might be able to find an appropriate "plastic sleeve" at McDonalds.

That is soooo unreal for as I was looking at T-Doug's original pic, I was wondering where is the original sleeve? Still in place?
