    Richard:

    According to my factory books, the 925/12 was used in '76-'77.

    Its geared:

    15/36
    21/30
    27/25

    Does anyone know if the "specs" can be find somewhere online so I don't need to bother you guys w/ these kind of easy questions?

    Hi Richard:

    I'm not aware that any of these kinds of specs are available on-line, but hopefully somebody will prove me wrong,...

    I use a collection of factory manuals & spec books.

    Please don't be afraid to ask for things like this as that IMHO, is the prime reason for these BBS's.
