Want to know how to tell the difference between D-106P (1931988) and D-112P (1966294?). Here's what I know from the two NOS sets in the picture.
Both have Delco Remy made in USA stamped on the bottom. The set on the left, in addition to the Delco Remy you can see on the arm near the pivot, has "PAT 2865726" on the bottom. This set came mounted on a "Plate Shield Pkg." (breaker plate, condenser, points set, 2-piece radio interference shield, ground lead, and misc screws). Box reads part # 1876065, with instructions dated 1972. On the right, the set came in a box clearly identified D-106P and 1931988.
At first glance, the main difference is the orientation of the attaching slots. Both fit on all distributor single point base plates. I pushed the cam rubbing block on both and about the same amount of spring tension was felt. But I understand that the D-112P is considered "high performance", so I'm wondering if the set on the left side is D-112P, or just another iteration of D-106P ?
Seems that the D-112P was used '66-up on all high performance motors (427's, LT-1's), with no grandfathering back to previous high performance distributors (L84, L76, etc).
I realize there is also a variation with suffix "PS" which I understand may mean the condenser and ground leads are attached with a screw, instead of just sliding the spade connector against the spring.
So is D-112P points set something entirely different from what is shown in the picture ? There's many offered on eBabe with this number (at a substantial premium over D-106P), and I'll be danged if I can see the difference.
