Thank you, for having the right parts I was looking for, all thou I am not using them on an aircraft, Im using them as replacement seals for exhaust and intake valve cages on a 1919 antique novo gas engine. They are the exact same size and style as the original equipment that came on these engines new. Also very fast shipping, Thanks again.

I bought this because I though I would need it to install oil temp gauge 10-11900, but I didnt need it because if you dont remove the adapter nut # 44-0024 its not necessary
