Need Fitting That Oil Filter Screws Onto

[jimlindenfelser]

See pic. I dont believe I removed this when I had taken engine apart to have machined so maybe the machine shop did. I do believe I may have seen this among the rebuild parts they gave me but did not know what it was. I could probably get one from my local pull and save. They have some Suzuki Swifts which I believe used the same block. What is it called and is there a source for buying one? Have not tried dealer.
