Question on the 86 series tractors. Someone told me that the 1976 year models was the only ones that had the black stripe on the side. They told me that IH was trying to use up the 66 parts so the 1976 86 models had 66 parts in them and had the black stripe. Any truth to this? Is that just for the 66 series or does that include the 86 series also. Does the 86 series have the black strip for only one year? I found a 1586 with a black stripe and didnt know if it was rare or not. I wish I could find a good International book with production information in it. Anyway any help would be appreciated.
