Hi, you can get both from Feked (just google it). See Scott Technicalities (you can google that also). You appear to need 1/4in ball bearings. If you need new cups there appear to be 2 sizes. Make sure you order the correct petrol tap thread. All the best and Season’s Greetings.
thank you for the informations. I have found the cups at Feked, but I have not found the right dimensions for my Flying Sqirrel 1936.
I need OD 2″ and ID 1+ 1/4″. At Feked I have only seen OD 2+3/16″ and ID 1 + 1/4″.
