Recently acquired a 1950 steering wheel with horn ring and button, including contact plate. Purchased Fusick upper and lower horn cushions. Trying to determine what other pieces are missing, and whether they are available or can be replaced.

Before investing the time and $ to restore the wheel and ring, want to be sure I can make it work/function. I saw an exploded view of the steering wheel and horn assembly someone posted online – very fuzzy and part names/numbers are not readable – but it looks as if there are at least two pieces missing that should go between the contact ring and the upper horn cushion (including one piece that looks like it attaches the whole assembly to the steering column).

Appreciate any information on what original or aftermarket parts may be needed to help get this in working order.
Also, if anyone has a clearer picture of the assembly, that would be helpful.

These are the pieces I have so far...

 

Does this help?

 

Thank you for this GREAT info - very helpful! Now I know exactly which parts I need - next step is to find them...

Appreciate quick and perfect response!

 

Google is your friend.
Google "Oldsmobile and the part number.
The part number will be a six digit number on the parts list.
The numbers on the illustration are group numbers and refer you to that group on the parts list.
Look in that group for your year and model, the part number will be listed with it.
You never know, you may turn up NOS parts that way.

 

Thank you - I started down the Google path and after several hours (well, at least it felt that way), found 3 of the four parts that were missing, including a NOS of the Contact Retainer. Only item left is the contact insulator. Based on another post, with great photos, I am going to attempt to recreate this piece. Will test all as soon as the NOS piece gets here - then it's on to making it all look great.
Again, greatly appreciate your assistance - having those part images and part numbers was exactly what I needed!

 

Glad to help.

 

Making progress, but cannot find any source for the insulator between contact and retainer (part # 554746). Does anyone know what material this insulator was originally made of? Or have any more info (photo or dimensions of an original part)? Very curious about the inside and outside diameter, and whether it wraps into the i/d or is flat. Diagram shows it extending down around each tab on the contact ring, but can't determine any additional "shape" that may be there.
Have considered several options to create the insulator function, but unsure whether it would be better to make it of hard plastic, rubber, or ?
And in a REALLY unlikely scenario, if you have one you are saving, would be interested in borrowing to replicate...
Thank you!
