They are the same as the single point versions: Delco D106P but I always preferred the screw terminal version D106PS. You can find them on eBay although my last Delco set was over 70 years old and would not fire until I made a single pass through them with a burnishing blade to remove the oxidation; after that, they were fine.
D112P Delco points have the 28 oz spring tension. Only needed for redline use and with the high spring tension they will wear out quickly.
The proper Delco points for your car would be D106. P is preassembled and S is the screw instead of the clip with PS having both features. D106 HP is a high performance point. Not sure exactly what that is but likely a stronger spring tension than the standard D106.
They are not the same, I bought D106PS and they are not correct. It's a 1111011 distributor Calls for D112P Points
Not certain the D112P points were even produced for your 1962 car. They first became available to the public around 1969-71. I learned about them and then ran them in my cars during this time. Later switched to ACCEL. But did use them again in my 1967 327/350 HP car beginning 1994-2022. Bought them as NOS off of Ebay.
But for your 1962 fuel car, the D106 should be just fine. They are good to about 5500-6000 RPM. Most folks don't push their cars past this anymore.
If I recall correctly the D106HP was more for heavy duty (truck) type applications with more electrical contact area, but lower RPM limit.
Delco points. D106PS after installing the gap was to wide and neither set would adjust. They are different than the ones I removed unless they are boxed wrong. I ordered a set of D106p delcos see what happens when I get them.
