For what it is worth, the part numbers (Piper, I believe) for the low profile oil quick drains are 492-283 (valve) and 481-357 (probe oil) plus you need a MS35769-11 washer. Total price $203.89. I ordered these beauties from Kansas City Aviation Center (913-782-0530) last year. They are pricey but make LIV oil changes a breeze.

 

I have not found any other quick drains that work due to the nose gear clearance issue. If you do put a quick drain on you aircraft make certain you do a nose gear retract test to ensure you do not have any interfernce that could cause an inflight loss of oil.
