The International Cessna^® 170 Association

I just bought federal 2500 ski,

I am looking for information for the federal A-2500A, ( instln. dwg. 11R170, mfg. dwg. ?? , picture of bushing, sleeve, bracket ...)

I want to make them as original as possible

Thank you

I found a document for the 1500 until 2000, are there people here who could tell me the difference for the A-2500A or it is exactly the same sketch and reference?
