Later model DP have the red sleeve. The D terminal is more of a copper terminal, the reproductions are not a perfect match so you can see the different. Also, can see in the pictures.

All the clocking also depends on the shaft and Cam Stop being correct for the application. Some cam stops have the flat for the rotor clocked in a different position, and some shafts have the tip slot oriented different.

So if you build motor correctly and follow svm for setting distributor drive gear slot correctly, and you put distributor in with vacuum chamber pointing correctly your rotor points to #1 plug. IF that does not match normal wire location, that normally means the distributor has some incorrect parts. If the camstop is a dp and correct rotation type Right or Left depending on motor, you just have to reorient wires. Or go get the correct parts for the distributor if you can find them.
