Speaker options for early C3 ?
Keeping the original Stereo radio in a 1970.
Anyone know of a speaker rebuild kit?
I see that there is a new replacement pair offered at CC and Zip: https://www.zip-corvette.com/70-77-4...rs-10-ohm.html
However, they are 8 ohm, not 10 ohm.
Anyone with recent experience with a company that rebuilds originals?
Are there any other options?

You will probably get away with a set of 4x6 plates that are 8-ohms as long as you're not cranking it for long periods of time. You could even add a heavy 2 ohm resistor (ceramic or such, 25w+ type of thing) in series to bring it up closer. The speaker impedance isn't linear while the resistor is so the sound will suffer some but the stock radio isn't going to be great anyway so you might not even notice....
Most aftermarket speakers are only 4 ohms and that's not going to work out.
If you're sticking with the stock radio I'd stick with the proper 10 ohm speakers so as to not risk hurting the radio

Try SM Electrotech. They should have the correct size and resistance speakers for your 70.

Keeping the original radio, I have found two options for speakers:
1. AC Delco 16033662. Now discontinued, but reproduced by OER here: https://www.oerparts.com/product/196.../16033662.html
The description claims a square magnet, this is BS....its round like the pictures show. This is a new 6x4 10-ohm speaker.
2. speakerex.com has a rebuild kit that is not listed on their site for unknown reasons. You must contact them to order.
Has anyone tried this rebuild kit?

Has anyone used these speakers and if so, how did you like them?
Crutchfield states they will fit a 75 under the dash as a direct replacement
