GM HEI "M4 pin" to female socket distr cap??

So.... I'm converting to GM HEI as many people have done. But I CANNOT find the right dang coil plug wire! The HEI coil is from a mid to late 90's truck/SUV and it has that odd "M4" or "pin" style terminal. I'm going from that to a traditional MOPAR cap with female socket terminals. It seems this should be a fairly common issue for us MOPAR guys but for the life of me I cannot find the right coil plug wire. All of the make-your-own wires have the normal male terminal to female socket. Can't find that odd M4 / pin style that GM used in the 90's.

Anyone else done this?? Many thank you's.
