Hi everyone, i installed one of these on my 1985 Argo when i put a 18hp brigg twin. Oil filter was knocking on the tranny and i wasn't abble to put the engine in the original TEC 16hp single mounting holes. Be sure to verify the price of thoses , because i return the base plate to connect the filter because it was too expensive. If you can find a good machinist, he could do it as bell with your original oil filter retainner... Hope it could help
