I honestly don't know if this filter is correct now or not. It did not used to be, but that was also 15 years ago. Personally, I have one of the semi custom spin on adapters that use a 7.3 spin on filter. Unfortunately that adapter has been out of production for many years, and there is really no way to get one other than find someone with one they want to sell. I have no idea how many were made, but I'd guess maybe 50 or so. There is also a Nissan spin on adapter that folks have used, I think it takes a rather odd filter, but I don't know for sure, as I have never had one. The correct canister element used to be very had to find and pricey, that's why I went to the spin on years ago.
