What's needed for stock steering wheel change?

Manual or power steering on your car? Manual steering you will hate the full circle horn ring wheel.

Manual. Yeah it's a workout :)

Yes they mount the same. Just be sure you get the mounting hardware and horn switch with the S79 wheel that I showed.

Yes but my question is what is the "mounting hardware" I need, that's what I'm trying to find out. :) Can't find anything online or with the major suppliers that's seems to be a "stock wheel mounting kit".

I also think you need the S79 horn switch - it is the tilting of the switch, byt pushing on the horn ring that blows the horn. On a 70 rim blow nothing tilts so I think the horn switch is different. If you get stuck send a pm and I'll take a pic of the correct s-79 horn switch and you can compare with the one on your rim blow.

There is no extension can used with either of these wheels.

Thanks, I figured I would need a new horn ring, at least I can find those online for sale and they're relatively inexpensive. The old steering wheel horn doesn't work anyway and the previous owner rigged up a doorbell switch on the dash that blows the horn (!!)
