positive ID for clutch pedals

[obijuank5]

I am getting old in my young age and cant remember which is which.

The pin location for the brake pedal is in a different location on each of these sets. I thought they were both hydroboost. Nice clean painted set has two holes. Can not confirm origin of either of these sets. Please confirm if you can. It seems to be tough to find the side by side differences online. Thanks

second set

First is vacuum pedal, second is hydro pedal. Lots of good resources in this thread:

Yes, the factory only had return springs on the hydro pedals.

Thank you for the link and clarifying photo. I did not at all look in the brake threads... noob mistake.
