Just want to soften up the ride. I am considering getting air-ride on it but want to see if I can get by with just swapping out the springs. I'm not interested in lowering or lifting the stock height if I decide to stick with the springs. Any one have any experience with putting c10 springs on a c20? I have coils on front and rear.

I would recommend going to the GM Heritage Center and download an information kit for a 1969 pickup. When you look through that document, keep any eye out for any ride heights specified. I would imaging that the 20 series rides higher than the 10 series anyway.
You can also see if a local spring shop can build a spring that has a softer rebound but you have to consider the handling characteristics of the truck, too. Having mismatched springs can lead to handling issues as well.
Personally, I'd leave well enough alone.

The heavy duty springs put into the C10 are C20 springs, so you can just as easily swap the other way too.

No such thing with springs. Rebound is controlled by the shocks.

The shock might dampen the rebound, but the spring going back into shape is what causes the rebound.

I see you smoke crack when talking about springs too.
You can get a softer spring rate, which is what C10 springs would do compared to C20 springs, but you can't magically make a spring with the same rate that rebounds softer or differently.
The OP doesn't need to be chasing spring shops asking for magic...

The suggestion was to get a spring with a softer rebound. Yes, that translates into a softer spring rate.
Get over yourself. You choose to argue about everything.
Let the OP decide on what they want. In the meantime, disengage with the hostility.

It's not simply rebound that is the issue. The shocks control both the compression and rebound. The heavy springs are probably not compressing enough over the bumps and pushing the chassis up instead of the chassis remaining stable and the suspension moving up.
Softer spring rate means;
It will compress more when the truck is loaded. You'll lose load capacity.
The spring needs to be longer to not lower the truck because it will compress more with the truck weight on it. It will also compress more when you hit the same bump allowing the suspension to better move up and over the bump instead of putting upwards motion into the chassis.
The stock factory rear springs are progressive rate, so they stiffen up as they are compressed. Done to help the load capacity of the truck. Most aftermarket springs are linear rate. Many are really low rates too.
