...not 100% sure what you are asking, but pedal spindle standards for modern clipless versus older toe clip pedals are the same. They all thread into the same hole.
If your question is one of aesthetics, (as in, in the 80's many people were still riding on older pedals and I want this to look authentic), then that's a different situation.

I'm not good with aesthetic problems. I'm a Philistine when it comes to aesthetics..
