> row type that only came in pre '83 engines.

> I discovered all of this because the original kit I got had the typical
> later model SINGLE row chain and gears, which I was told by the supplier
> superceded the double row chain and gears and GUESS WHAT...?!

> I took it back, got a kit for an '82, and SURE ENOUGH, it was the double

> Interestingly, the pre '83 kit that I got from Federal-Mogul comes

> '83 and up - KT-1020S (single)
