Default MSD Vented Opti Wiring Harness

Hey guys, I am in the process of reassembling my motor and have seemed to run into an issue. My Corvette is 1994 but I ordered the 1995 timing cover, new LT4 Hot Cam and the vented MSD (83811). My issue is the original distributor connector is different from the MSD (see pictures below). Is there an adapter harness available or can I buy a new connector for the Corvette (95+ distributor)?

I would call MSD or Summit...maybe Ecklers and ask them.

While researching Optisparks, I came across a seller with that connector. As I recall, the longer of the two small pieces of plastic (on the right in photo) inside the black connector gets snapped off with needle nose.
