The housing is definitely an 65 style was the oil deflector an option back then, Fred could probably answer that, my opinion is no, it was probably added by a previous owner, like I said earlier the Kar was most likely used for drag strip, you sure wouldn’t want an open rear gear for that. I posted a long article in the old forum about this Kar at the time of purchase, I’ve rebuilt practically everything on this Kar, the third member is hopefully the last thing. A couple of pictures of the rear that came out of Kar, it’s definitely some sort of locker.

The 65 Hipo was not available with a locking rear end. The locking rear end became an option in the 66 model year on a Hipo. The 66 axle housing remained of the 65 style until some time in October of 1965. Therefore that style of housing would have been available with a locking rear end in that time frame of the 66 model year.
