I need any help you guys can give me . Im fixing up an old berkel model GA and I have a couple questions that you guys may be able to help with . I need a new belt but Im having trouble locating one . The number on the belt says 4702-5 . I cant seem to find this number or a cross for it . Also the slide oil tube wicking material was gone . Its the flat stuff that fits into the tube . The new stuff I ran across is 50 bucks for a small piece . Have any of you used a substitute material . I was wondering if felt or flat oil lamp wicking might work . If any of you have any ideas I could surly use the help . Thanks much
