    Since you've got the cover off just count the ring gear teeth and the pinion gear teeth and divide the two. 41 ring gear teeth / 10 pinion = 4.10 /forums/images/graemlins/thumb.gif

    10 41 is the ratio, 10 is pinion teeth and 41 is ring gear teeth so they are 4.10's. 1 76 is the build date...January 1976.

    Nice for sale ad at the end of your post. That is against the site rules unless you're a paying member here. Even then there is a specific forum for parts wanted/sale.

    That is a for sale ad, nothing to get offended about, but it is against the site rules. Pretty simple stuff...

    Trust me, you're not the first one trying to slip one under the radar here. This post will likely be gone soon enough.
