Are these connectors available?

Replaced the turn signal switch in my 66 Barracuda and found that the previous owner had once done the same, but didn't really finish the job correctly.

They spliced the wires into the connector block but broke the tabs that hold it together. Are these available new or reproduced? I couldn't find any, so hoping for some direction.

Would also appreciate any guidance on placing the signal canceling cam on the back of the steering wheel. I have no idea why, but they removed it from the wheel (along with several other pieces). A picture of how it relates to the spokes (2 spoke basic wheel) would be great.

Thanks!
